Full textAbstract:
The purpose of this prospective clinical study was to investigate differences in outcomes from two common treatment modalities used to reduce deep overbite: maxillary incisor intrusion using an intrusion arch and posterior tooth eruption using an anterior bite plate and to assess their influence on smile esthetics. Pre-treatment and post-overbite correction records were gathered from 40 patients with deep overbite malocclusions at the Virginia Commonwealth University orthodontic clinic. Intrusion arch patients displayed significant reductions in maxillary incisor display accompanying documented incisor intrusion. Bite plate patients showed significant lower incisor intrusion and increases in the mandibular plane angle. When compared to the bite plate group, there was a greater tendency for flattening of the smile arc seen in the intrusion arch group. Changes in the smile arc were likely partially a result of the mechanics used but may also have been due to other factors involved in orthodontic tooth alignment.

Full textAbstract:
Delamination is recognized as one of the most critical defects that can result from the machining of composites. Delamination has been a major form of failure in drilled composite materials due to the composite’s lack of strength in the direction of drilling, which results in poor surface finish, reduction in bearing strength, reduction in structural integrity, and ultimately poor performance of the composite. Delamination due to drilling has been a major research interest for many years, and a considerable amount of work has been done to reduce it. This thesis work involved deriving a formula to determine what applied thrust force would cause delamination in a particular drill bit, the multi-facet drill bit. To achieve that goal, a formula was developed. The conditions and the drill bit used were altered. The thrust force at which delamination occurred was dependent on the thickness and the composition of the material being used. Experimental validation of the physical model involved calculating the thrust force that would cause delamination, using the formula, and drilling at the calculated thrust force. The thrust force was applied as a correlation of feed rate and spindle speed.<br>Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Mechanical Engineering

Previous issue date: 1997<br>Resumo: Foram examinados e tratados dez (10) pacientes do sexo feminino, na faixa etária entre 23 e 50 anos de idade, com sinais e sintomas de alterações funcionais do sistema estomatognático, divididos em dois grupos de cinco pessoas cada. Um grupo foi submetido a tratamento com aparelhos de cobertura oclusal plana e, o outro grupo tratado com aparelhos de pistas duplas tipo Planas, 1987. Os sintomas relatados com mais freqüência, foram as dores de cabeça seguidas de sensação de desconforto muscular. Todos os pacientes foram submetidos aos seguintes procedimentos: anamnése, exame clínico, exame físico através da palpação muscular, moldagem e modelos de estudo. Além dos exames e procedimentos preliminares, foram realizadas duas fases laboratoriais: uma para a captação dos potenciais elétricos dos músculos estudados e, a outra fase para o enceramento dos aparelhos em articulador semi-ajustável e respectivas prensagens em resina acrílica incolor termicamente ativada. Os aparelhos foram instalados e neles foram realizados os primeiros ajustes em relação aos dentes antagônicos. A primeira captação dos potenciais elétricos ocorreu antes da instalação dos aparelhos; a segunda aos 30 dias de uso e a terceira, após o refinamento oclusal, por volta de 60 a 120 dias do início do tratamento. A análise dos potenciais elétricos obtidos durante o período de tratamento com aparelhos de cobertura oclusal plana e do tipo Planas, com a mandíbula em posição postural, na mordida incisivo com resistência, na mordida molar com resistência e mordida molar sem resistência, evidenciou que os pares de músculos estudados, funcionalmente, com o decorrer da terapêutica proposta, tenderam a se equivaler. Em relação ao tipo de aparelho utilizado, ambos mostraram-se efetivos, sendo o de melhor manipulação, os de cobertura oclusal plana. O ajuste oclusal por desgaste seletivo, mostrou ser, importante do ponto de vista da manutenção da posição da mandíbula, conseguida com o uso dos aparelhos intra-orais, quando avaliado através da captação dos potenciais elétricos dos músculos estudados e do relato da remissão dos sinais e sintomas clínicos<br>Abstract: Ten female patients, with age between 23 to 50 years old, were submitted to a clinical examination and were treated with intra oral appliances, since all of them presented symptomatology related to functional alterations of the stomatognathic system. This group of 10 patients were divided into two groups of 05 patients each. The first group started the treatment wearing flat occlusal splints and the second group started the treatment wearing Planas's appliances with functional tracks (1987). The major and the most importants complaints of all patients were headache followed by muscle discomfort sensation. The all patients were also submitted to anamnesis and during the clinical examination a muscle palpation was perfomed by the professional as well as the impression of the jaws followed the execution of the respective stone cast models. Two laboratory procedures were also realized, firstly for determination of the eletrical potential of the masseter and temporalis and after for the waxing, the appliances were fixed in semi-adjustable articulador and were posteriorly cast with an incolor acrylic resin activated thermically. The appliances were installed in the respective patients mouths and the first adjustments were realized based on the antagonists teeth. The determinations of muscle electrical potentials were performance, firstly, before the instalation of the appliances, after 30 days of their usage, and finally in the period between 60 and 120 days after beggining of the treatment associated with the occlusal adjustment. The muscle electrical potential were obtained during the treatment of the 2 groups of patients, with the respective intra oral appliances referred previously, with the mandible at differents positions such as: postural position, incisor bitting with resistance, molar bitting with resistance and molar whithout resistance, showed that the pair of muscles studied had a functional behavior similar to each other independently of the treatment proposed.<br>Mestrado<br>Protese Dental<br>Mestre em Clínica Odontológica

Previous issue date: 2011<br>Resumo: Apesar dos diversos tipos de fixação interna existentes ainda não há um consenso quanto ao método de imobilização das fraturas do ângulo mandibular. Além disso, são poucos os estudos sobre a utilização de placas grade ultimamente lançadas no mercado. O presente estudo visou avaliar comparativamente a resistência entre três tipos de fixação interna em réplicas de hemimandíbulas de poliuretano seccionadas na região de ângulo mandibular, simulando uma fratura linear. As formas de fixação incluíram a utilização de placas em forma de grade com e sem barra intermediária e o método descrito por Champy (1978). O objetivo foi definir por meio de análise mecânica a técnica que permitiu maior resistência na fixação deste tipo de fratura. Os testes de carregamento linear vertical foram realizados em amostras de cada grupo estudado (n = 10) utilizando uma unidade de testes mecânicos para registro da carga atingida, nos momentos que o deslocamento vertical alcançou 3 mm e 5 mm. Médias e desvio padrão foram avaliados aplicando-se a Análise de Variância e o teste de Duncan em nível de significância de 5%. Concluiu-se que a técnica de fixação interna para as fraturas de ângulo mandibular descrita por Champy (1976) foi a mais resistente e, que a inclusão de barra vertical intermediária nas placas grade não ofereceu aumento da resistência quando comparadas às placas grade sem barra<br>Abstract: Although there are several methods of stable fixation, there is no consensus about the treatment of mandibular angle fractures, Also, there are few studies about grid plates recently commercially available. This study compares the resistance of three fixation methods in polyurethane hemimandible replicas. Those were osteotomized at the angle region to simulate a linear fracture. Fixation methods were four-hole 2.0mm grid plates with and without a vertical intermediate bar and 2.0mm four-hole straight plate. The objective was to determine, through mechanical analysis, the fixation method that results in greater resistance to displacement. The hemimandibles were submitted to vertical linear loading in a mechanical test unit for registration of load after displacement of 3 and 5mm. Means and standard deviation were determined. Variance analysis and Ducan's test were applied considering a significance level of 5%. Results showed that the 2.0 four-hole plates, positioned according to the Champy technique, provide greater stability than the grid plates. When a vertical intermediate bar was added to the grid plates, resistance of the system was not increased<br>Doutorado<br>Cirurgia e Traumatologia Buco-Maxilo-Faciais<br>Doutor em Clínica Odontológica

A variety of practical examples are presented to show the effectiveness of the proposed model, making use of the generalised Green's function for the half-plane. Furthermore, the present method has been investigated assuming a "weak interface" to simulate the behaviour of adhesive between two materials. The relationship of slip and interfacial reaction is supposed "a priori" linear elastic or elastic-plastic. The simple linear cases are compared with the Melan's solution. Debonding of a FRP-strengthened reinforced concrete substrate has been reported and confronted with experimental results and prediction of another model found in the literature. Finally, zero-thickness interface elements are used in the 2D finite elements to reproduce a brittle fracture within a laminate substrate.

providing video services using wireless telecommunication networks.
The stages of creating a method for controlling the intensity of video frames at the level of encoding frame segments and their structural components are described, the basic features of which are that for each segment a code description
is formed in the form of a set of independent code structures. This allows you to control the bit intensity of the video by changing the number of structural components of the code structure of the transformed frame segment. The method
allows to reduce the redundancy of the video frame description by taking into account the structural features of the description of transformants at the level of bit representation.
The expediency of an approach based on the exclusion of a number of transformants of a video frame segment with subsequent interpolation to construct a method for controlling the intensity of a video stream with a controlled level of
quality is substantiated.
A method for controlling the bit intensity of video traffic is being developed based on downsampling of frame slices at the transformants level with their subsequent interpolation, while processing the video stream in real time is provided.
To implement the method for controlling the bit rate of video traffic based on downsampling of slices, sets of basic transformants and transformants are preliminarily formed in their structure, which can be thinned out at this stage.
Within the framework of the control method, the existence of modes of operation is provided, during which the bit intensity is changed in real time and the error level is corrected, which can be introduced in the process of controlling the value of the video bit intensity.

Full textAbstract:
碩士<br>國立臺北科技大學<br>電腦通訊與控制研究所<br>90<br>In this thesis, we develop a robust bit-plane watermarking technique for SPIHT-coded images. A robust watermark is an imperceptible but indelible code that can be used for ownership identification. The SPIHT coding is popular owing to its high coding efficient, low coding complexity, and the capability of generating scalable bitstreams. Efficient image compression and watermarking algorithms use similar techniques to reduce the introduced visual artifacts. In contrast of the conventional approaches where compression and watermarking are treated independently, the proposed method integrates these two operations. The watermark is inserted by directly modifying the output bitstream of the SPIHT encoder. Since the watermarking framework is tightly coupled with compression, we can avoid adding watermark information to the coefficients that would be susceptible to quantization errors. Furthermore, this compressed-domain watermarking framework may reduce the system’s complexity since watermark embedding and retrieval may be performed directly in the compressed domain. Security of the system relies on the secure keys that determine the watermark signal and watermarking locations. Complete evaluation is conducted against both noise-type and geometric attacks. By analyzing the error patterns that each attack generates, we develop appropriate techniques that enhance the robustness of the system. Experimental results show that our method survives the aforementioned attacks and the performance is better than that of transform-domain approaches.

With technique of image decomposition into bit planes, the independent analysis and processing of bit planes are used for image compression. In this paper, an adequate algorithm denoted Adjacent Decomposed Bit-Plane Substitution (ADBPS) is proposed to achieve benefits of both high image quality and compression ratio. The ADBPS uses the characteristics of binary combination between adjacent bit planes, basically without change of the most important spatial information, to achieve an ADBPS Transform Model. To evaluate the performance of the ADBPS, we can theoretically calculate the bound of both probability of image distortion and compression ratio. The experiment conducts 2 cases, w/MSB transform or wo/MSB transform, which are based on commercial WINZIP coding method for final performance evaluation. The results show that the ADBPS scheme, with the ADBPS transform model, outperforms the morphology model much higher image quality and good compression ratio.

Full textAbstract:
碩士<br>國立中正大學<br>資訊工程研究所<br>105<br>In recent years, video surveillance has become increasingly popular, the development of video surveillance technology is indispensable, because it can reduce labor costs and detection error rate. Most video surveillance cameras are fixed, so there is an increased demand for background modeling. When the motion object appears in the video, the moving object is called the foreground object, which can be extracted by "background subtraction". In the video monitoring, moving object detection has become one of the core technologies of automatic understanding of video content. Although a number of detection methods have been proposed, they still have some problems, such as shadows and incomplete shapes of moving objects.
In this thesis, we use the Bit-planes method for the motion object detection in the video surveillance system to generate the hyper bit-plane by the color information and YUV color space information. Hyper bit-plane uses the YUV color space information to suppress the shadow growth, and our method uses hyper bit-plane as the indicator image. In order to describe clearly the complete contours of moving objects, the use of grayscale Bit-plane image as a lower benchmark image information, and use spatial and temporal information to integrate hyper bit-plane and low Image information results, that applied to the image hysteresis threshold and motion compensation to compensate for the loss of space and time information, that can obtain complete foreground through the hysteresis threshold and motion compensation. Finally, we will be able to use the method in the real-time surveillance system.

Masters Research - Master of Philosophy (MPhil)<br>This paper examines how memory, knowledge and connection are imbued in place. Considering how place can inhabit self and self can inhabit place. This proposition is reinforced by looking at many models and cross cultural examples as well as the work of theorists such as Casey, Relph and Blowby. The proposition that we are strongly related to our geographical locations, and by considering the similarities in make up of the earth to our bodies, a case is made that we are biologically and chemically part of the land. This becomes so by acknowledging that what we eat is of the land and hence there is a strong correlation between the two. It is then considered that since we are part of the land the land in turn becomes part of us. The off campus performance work On becoming a Witch provided a very powerful link between the exegesis and the studio work. It examined yet another way in which one is able to relate to country by the use of ritual, myth and symbolism in a specific bush setting. It brought together skills related to theatre, opera, costume design and music. This has been fully documented as part of the exegesis. The studio component of this thesis examines how one can closely relate one’s paintings and drawings to a sense of place and country by the use of materials such as ochres and the use of strong simple abstract forms. The use of a dominant symbol, the ziggurat, has been explained as well as the processes used with the result being a series of strong paintings and drawings. These act as a tangible link between self and a sense of place.

Full textAbstract:
碩士<br>國立交通大學<br>電子研究所<br>98<br>This thesis addresses the problem of reconstructing a compressively sampled sparse signal from its lossy and possibly insufficient measurements. The process involves estimations of sparsity pattern and sparse representation, for which we derived a vector estimator based on the Maximum a Posteriori Probability (MAP) rule. By making full use of signal prior knowledge, our scheme can use a measurement number close to sparsity to achieve perfect reconstruction. It also shows a much lower error probability of sparsity pattern than prior work, given insufficient measurements. To better recover the most significant part of the sparse representation, we further introduce the notion of bit-plane separation. When applied to image compression, the technique in combination with our MAP estimator shows promising results as compared to JPEG: the difference in compression ratio is seen to be within a factor of two, given the same decoded quality. More than this, we also applied such framework into the application of multiple description coding. According to the simulation results, our MAP estimator is very resilient to the loss of measurements, showing an acceptable quality while coping with a highly loss channel. In conclusion, our CS framework using the MAP estimation can provide a much better compression efficiency and stronger functionality of error-resilience, compared with other prior work.

Full textAbstract:
碩士<br>國立成功大學<br>電機工程學系碩博士班<br>90<br>Since FIR filters have a wide variety of applications in the field of digital signal processing, a high-speed low-cost architecture of FIR filters is strongly required and many architectures have been proposed. Among these architectures, they are categorized into bit-serial, bit-parallel, and digit-serial in the level of bits. The intention of bit-serial is to trade time for hardware cost and suitable for medium and low speed applications. Although bit-parallel needs high hardware cost, it is however suitable for high speed applications. Digit-serial owns the property between these two schemes and is fit for medium speed applications. In different cases of applications, we need to adopt different architectures and even need to invent a new architecture to achieve the goal.
This paper proposes an architecture whose input signal is bit-serial in the level of bits. Hence, the operation of multiply is reduced to a mux of selecting fiter coefficients and zeros. This makes the whole operations of the filter become the additions of fiter coefficients, therefore the great reduction of hardware cost. This architecture saves more hardware cost than radix-4 booth based architecture. In addition, we take advantage of retiming to further reduce the propagation delay in the critical path of this architecture. This processing makes our architecture achieve a very high working frequency.
The proposed architecture not only saves hardware cost but also works in a very high working frequency. Especially when the bit number of filter signal or the length of filter increases, this architecture still keeps its strengths. Therefore, the proposed architecture has a wide range of applications.

Full textAbstract:
博士<br>國立成功大學<br>資訊工程學系碩博士班<br>96<br>The purpose of this dissertation is to exploit the relationship between compressed audio and the coder-related characteristics to develop new algorithms when bit-plane coding strategy is applied on the Modified Discrete Cosine Transform (MDCT) domain. The bit-plane coding method has been extensively investigated in image compression domain and standardized in JPEG2000. It successfully combines the hierarchical content of the Wavelet transform with a set of progressive scanning and coding operations to achieve a sub-optimal performance in both quality and transmission scalabilities. There are two difficulties when researchers attempted to use the same compression strategy in developing scalable audio compression methods. The first difficulty is that human aural perception is quite different from human visional perception. New methods are needed to guide the order of the importance of transformed coefficients. Huge research literatures discussed the audio perceptual coding effects in the generic Fourier domain but less in the Wavelet domain. It is hard to determine coding strategies without appropriate audio perceptual criterions in the Wavelet domain. On the contrary, as one of generic Fourier transforms, the MDCT has been developed for audio coding for decades and is practically proven an outstanding tool. Different from the Wavelet transform applied to the image compression, the MDCT coefficients of an audio piece lack a hierarchical self-similarity structure. The second difficulty is revealed here that the coding efficiency of the progressive coding strategy may not be maximized without such kind of self-similarity context.
By understanding the zero-tree assumption of the context-based bit-plane coding, the author tried to analyze coding efficiencies of different ordering schemes to avoid the lack of self-similarity context in the MDCT representation；Two original contributions in this dissertation are presented. The first part is to provide a systemic analysis between the ordering scheme and the coding efficiency for zero-tree based bit-plane coding strategies. This analysis gives a strong groundwork for the follow-up researches. The second part consists of one novel bit-plane algorithm and one corresponding bandwidth extension algorithm. This integrated design demonstrated a progressive methodology from the low-level data representation/compression to the high-level parametric synthesis.

碩士<br>國立交通大學<br>資訊科學與工程研究所<br>100<br>For the recent decades, digital video technology has been popularly used and become a necessary part in our daily life. With the development of digital signal processing and demand of better coding performance, H.264/AVC is regarded as the international video coding standard for the next generation. Video compression allows the reduction of high-resolution video into a more compact memory space to thereby reduce storage and video processing resources during playback.
Along with the benefits is extremely large amount of computation, and a large number of fast algorithms had begun. Thus, how to balance quality and speed of operation becomes the most important issue, which is the subject of this paper.
According to the literature published before, we can find that the motion estimation process and mode decision are the most time consumed part. The conversion of One_Bit Plane Transform (OBPT) is used to reduce the complexity of motion estimation. And this paper we proposed will apply the OBPT in mode decision so that the complexity of compression will reduce and it will not make the compression quality declined.

碩士<br>國立高雄第一科技大學<br>電腦與通訊工程系碩士班<br>106<br>According to the Ministry of the Interior, the ratio of the number of elderly people aged 65 and over to the total population in Taiwan is 14.05%. Taiwan has become an aging society. The health care and disease prevention of the elderly is an important medical issue in the future. Among them, electrocardiogram is an important medical information widely used in the diagnosis of heart disease. In order to facilitate remote monitoring and long-term ECG data recording, the use of wireless wearable devices is one of the most feasible methods. The wearable device system includes three parts: electrocardiogram signal sensing, data compression and wireless data transmission. Data compression is an important function, and the purpose is to reduce the amount of data transmission so that the working time of the device can be extended to record data for a long time. Since ECG has medical value, ensuring the stability of reconstructed data quality is a basic requirement for ECG data compression. In order to combine the real-time data compression function and the quality assurance mechanism, in the preliminary research, we developed a wavelet transform data compression system based on the simplified distortion index (SPRD2). The system consists of three parts: a reversible round-off non-returning discrete periodic wavelet transform, a nonlinear quantization process with quality assurance mechanism, and a distortion-free improved hierarchical tree set partition coding. However, the 11th-order quantization is still in the traditional way, requiring complex hardware and unfavorable wearable device applications.
In order to overcome this difficulty, this paper proposes a wavelet coefficient quantization algorithm based on bit plane. This algorithm consists of three procedures: initial quantization factor (QF) estimation, error calculation, and QF refinement. First, using the error limiting condition, the quantization factor starting value 〖QF〗_0 is estimated from the original signal 〖 S〗_j, 〖QF〗_0 is reflected in the threshold BPL on the bit plane, and the bit under the statistical BPL is the actual distortion (〖ERR〗_pr). Let the preset distortion limit be 〖ERR〗_pr, and the QF refinement area can be defined as ∆ERR=〖ERR〗_pr-〖ERR〗_up. The refining procedure gradually resets ∆ERR to zero by searching for the finite bit quantization factor and the BPL correspondence table. From the experimental results, we can control the error within a certain range, the number of QF searches is effectively reduced, and the compression ratio is not lost due to the lowering of QF.

Full textAbstract:
碩士<br>國立清華大學<br>電機工程學系<br>91<br>In recent years, video transmission is rapidly developed and widely employed in various applications; however, no matter the traditional wired network or the latest wireless network, they are all evolving to packet-based but currently provide no or limited end-to-end QoS guarantees. Packet loss is unavoidable when real-time video is to be transmitted over the networks. In order to overcome the problem, based on the concept of multiple descriptions (MD) coding, we propose a new MD coder: Multiple Description Bit-plane Coding (MDBC) which combines the alternative and duplicate schemes to produce two descriptions to be transmitted over networks.
From the experimental results, when the bit rate is 144kbps, our MDBC coder outperforms conventional coders in average by 5.54 dB, 6.75dB and 2.77 dB for Akiyo, Foreman, and Stefan sequences, respectively. Besides, for comparison with different MD coders, we also present the performance of MDSQ. At packet loss rate of 10% and 20%, our MDBC provides about 0.23dB, 0.23dB, and 0.38dB in average better performance than MDSQ for Akiyo, Foreman and Stefan sequences, respectively. However, for the same sequences, our MDBC has 1.04dB, 0.34dB and 0.14dB loss in low packet loss cases.
For the packetization in common MD coders, we propose Interleaved Packetization which utilizes two different scan orders to packet MBs into video packets of two descriptions. Therefore, the probability that descriptions of adjacent MBs are lost simultaneously is reduced significantly so that the performance of the error concealment can be improved. In our experiment, on the average for all packet losses, our interleaved packetization is superior to raster scan by more than 0.44 dB PSNR in average.

碩士<br>國立中央大學<br>電機工程研究所<br>98<br>In JPEG2000, embedded block coding with optimized truncation (EBCOT) requires a lot of computations. To enhance the performance of EBCOT, an efficient EBCOT algorithm is proposed. This algorithm consists of pass-prediction and pass-propagation. Pass prediction predicts the pass state in the next bit-plane. In particular, pass propagation generates the state of neighboring passes in the next bit-plane. This work also accomplishes boundary pass classification. With the propagated state, the pass state of the code-block can be classified for indicating the correct coding method. Various simulations have been conducted. The experimental results show that the proposed algorithm reduces the number of scan cycles by 42% to 52.7% for gray-level images and 11.8% to 34% for color images. The comparison demonstrates that the performance of our proposed method is higher than that of previous methods.
We implement this algorithm on a digital signal processing platform, with optimization of program and configuration, the encode time of encode images reduced from 23.25 second/per image to 2.71 sec/per image on the platform. The JPEG2000 encoder is applied to a photograph system, user can decide encoded file size according to the image quality or compression ratio which user selects.

According to this problem we should make error resilience to raise quality of transferred image after we get it in receiver side.
In this paper,we suggest a structure of error resilience in encoder and error concealment in decoder. And we take a schema of unequal error protection,UEP ,we make groups of significant bit plane and insignificant bit plane.For significant bit plane we enhance protection to have ability of error resilience and for insignificant bit plane we use quadtree structure to compress the data.So this method has two properties ,one is error resilience and the other is small transferred data bits.Based on this method,video data is also the same as static image,and we make four partition in each image of video data,and then interleave these images to decrease error block size in one image.By this way,we can raise quality of decoding image.And then after decoder accept the image,we can first identify error condition to choose a optimal algorithm to do error concealment to get optimal quality of image.
After implementing this algorithm ,we make sure this algorithm is really a solution in wireless network ,it is adaptive to be used to transfer multimedia data in wireless network . So we can scale transferred data bits to fit the network and the mobile device .At last , because we use Haar wavelet transform , it decrease complexity of hardware ,by this we found this algorithm is really adaptive for wireless network .

The proportion of medical resources that can be expected from the health care of the elderly will grow rapidly year by year, in which the long-term recording and differentiation of ECG (Electrocardiography, ECG) is one of the key projects, Widely used in the diagnosis of heart disease in the bed.

The wearable device system includes three parts, such as ECG signal sensing, data compression and wireless transmission, in which the purpose of data compression is to reduce the amount of traffic data in order to prolong the life cycle of the device and to facilitate long time data recording.

The traditional scale quantification is still used in the one-order quantification (Scalar quantization; SC), requires a high cost of division operation hardware, adverse application of wearable devices
In order to overcome this difficulty, this paper proposes a quantization algorithm of non-removal wavelet coefficients based on bit plane. This algorithm contains five programs : Calculation of upper and lower limits of distortion、Initial quantitative scale THBP estimation、Distortion qe calculation、THBP refining、Quantization mode Huffman coding. First, the THBP starting value is estimated by the original signal SJ and the upper and lower limits of the error are calculated. The THBP is projected on the place plane, and the number of digits under THBP is the actual error of qe. The upper and lower limits of the error are Errorup and Errorlow respectively, and the THBP is refined to the qe eligible Error_low≤qe≤Error_up. Refining algorithm is when the distortion degree is greater than Errorup tuned reduce the frequency of the THBP, the distortion is less than Errorlow to increase the high frequency of the THBP, gradually converge the distortion to the error range. The 48 electrocardiogram in MIT arrhythmia database was used as the experimental object, and each 15 minutes was divided into 316 segments. The experimental results show that the number of refinements is up to 22 times, the lowest 0 times, the average 5.62 times, and the average compression rate is 10.78 in the case of reconstruction of mass SPRD2=3%±0.05.

碩士<br>國立臺灣科技大學<br>電機工程系<br>104<br>This paper analyzes JPEG2000 embedded block coding and a design of efficiency optimization in detail. In JPEG2000 systems, the EBCOT requires considerable computation. In order to improve the efficiency of EBCOT, we integrated the two speed-up algorithms - Pass Prediction and Sample Skipping. The Pass Prediction algorithm predicts the pass state in the next bit-plane, and acquires the entire pass states in the next bit-plane through pass propagation of neighboring bit. According to EBCOT coding rule, once a bit has been coded by a certain pass, it will require no more coding by another pass. With the traditional coding algorithm, a bit that has been coded by a certain pass will still have to go through all pass scanning again. To distinguish the bits that require coding and those don’t require so, Sample Skipping marks the bit which has been coded; in this way, the compressing and scanning time that used to be wasted on the coded bits is now saved up. The results of our experiment show that the proposed algorithm reduces 6.2%~7.3% the amount of scanning time for gray-level images and 9.2%~18.6% the amount of scanning time for color images in loosy compression ,and reduces 14.2%~20% the amount of scanning time for gray-level images and 10.7% to 16.8% for color images in lossless compression.

碩士<br>國立交通大學<br>資訊科學與工程研究所<br>106<br>Read disturbance is a circuit-level noise induced by flash read operations. Read refreshing employs data migration to prevent read disturbance from corrupting existing data. However, it costs frequent block erasure under read-intensive workloads. Inspired by software-controlled cell bit-density, we propose to reserve selected threshold voltage levels as guard levels to extend the tolerance of read disturbance. Blocks with guard levels have low cell bit-density, but they can store frequently read data without frequent read refreshing. We further propose to convert a high-density block into a low-density one using in-place reprogramming to reduce the need for data migration. Our approach reduced the number of blocks erased due to read refreshing by up to 85\% and the average read response time by up to 22\%.

Pattern matching method is able to provide accurate positioning services. However, the positions of sensor’s chips are different for smartphones. A sufficient number of Received Signal Strength Indicator (RSSI) values are required to be stored into the database for each smartphone at the offline stage.
In this paper, we proposed a bit-plane clustering technology to divide the collected RSSI values into N bitmaps. The goal of this work is to reduce the numbers of database RSSI at the offline stage and to speed up the connection time at the online stage. The bitmap separated many layers from the most significant bit (MSB) layer to the least significant bit (LSB) layer. After training, the same characteristic bitmaps were clustering into one group. In this study, bit-plane clustering technology compared with different positioning methods, such as RADAR, K-Nearest Neighbors algorithm (K=2), correlation method, and pattern matching, the positioning accuracy at 1 meter in environment 1 increased about 13.7% ~ 33%, 22%~44%, 16.7%~100%, and 44 %, respectively. In environment 2, the positioning accuracy compared with RADAR, correlation method, and pattern matching at 1 meter increased about 22%, 13%, and 62%, respectively.

碩士<br>國立中興大學<br>電機工程學系所<br>107<br>Image compression is one the major techniques in various space missions and remote sensing systems. Consultative Committee for Space Data Systems (CCSDS) has developed a data compression standard for the tasks on the satellite. This algorithm is based on JPEG2000 and SPIHT. The purpose is compressing the satellite imagery and transmitting it to the ground earth station in real time while trying to reach the balance between memory buffer requirement and image quality.
The CCSDS IDC algorithm consists of two major functional parts: Discrete Wavelet Transform(DWT) and Bit-Plane Encoder(BPE). DWT module aims at data decorrelation. After decorrelation, BPE module then encodes the coefficients decomposed by DWT and supports the options of data rate control and image quality adjustment. In thesis[1], both floating type and integer type DWTs have been implemented by using a 9/7 filter architecture. Both of them perform a 2-dimentional 3-level DWT decomposition with adaptive image width settings.
The bit plane encoder is the key module of CCSDS IDC system. It is also regarded as the bottleneck of throughput performance and hardware resource consumption. This thesis presents an efficient VLSI architecture design of BPE hardware accelerator. It takes the result of DWT module as input, and employs an interface circuitry to cope with the throughput rate of the DWT module. The interface circuitry also reorganizes the received DWT coefficients from a word-level ordering to a bit-plane level ordering, which facilitates the processing of bit-plane based encoding. Parallel and pipelined processing techniques are adopted extensively in the BPE module design to achieve the target throughput rate. In addition, a ping-pong buffer strategy is employed to meet the throughput requirement of holding the generated symbols and bit-streams. The BPE design is verified by comparing the results generated by the software simulation model and the Verilog model. Due to the data dependence in BPE generated bit streams, the verification is conducted step by step to ensure the functional correctness of each module in the BPE design. The BPE module design is implemented in a Xilinx Virtex-7 XC7VX330T FPGA device with a maximum clock frequency of 87.41 MHz. This suggests a throughput rate of processing up to 10,000 8,192-pixel-wide lines per second.

碩士<br>國立高雄第一科技大學<br>電腦與通訊工程研究所<br>99<br>Electrocardiogram (ECG) signal analysis is a non-invasive modality widely used for heart disease clinical diagnosis. For accurately determine the patient''s cardiac status, physician usually depends on the quality of the recording signal. Among many ECG data compression methods, wavelet-based approaches with high compression performance have attracted much attention from researchers The SPIHT scheme can be very efficient for data inherent in hierarchical self similarities. However, this scheme exploits the self similarities in terms of dynamic data structures that will impose practical limitation on hardware implementation, especially for large-size data sequences. In this thesis, a modified set partitioning in hierarchical trees (MSPIHT) Algorithm is proposed for solving these problems. Different from SPIHT, the MSPIHT used the bit-plane and flag concepts, which can reduce memory requirement and speed the coding process. Besides, we combine three lists, LIP, LSP, and LIS, in SPIHT coding process into one step to simplify the complexity of MSPIHT coding process and use check bits to reduce the offspring coefficient searching time. Comparing with SPIHT, the proposed MSPIHT has more regular coding process, lower coding complexity, and shorter coding time.

A Modified Set Partitioning In Hierarchical Trees (MSPIHT) Algorithm was proposed for solving these problems. Different from SPIHT, the MSPIHT used the Bit-Plane and flag concepts, which can reduce memory requirements and speed up the coding process. Besides, three lists in SPIHT coding process: LIP, LSP, and LIS were combined into one step to simplify the complexity of MSPIHT coding process. The searching time of descendant coefficient was also reduced by using Check Bit. Comparing with SPIHT, MSPIHT had more regular coding process, lower coding complexity, and shorter coding time.
In this study, we utilized ALTERA DE2-115 as a platform to implement MSPIHT coding by using SOPC. According to the experiment result, the hardware could be exactly implemented. Furthermore, MSPIHT encoding process was 70-90 times faster than SPIHT, and reduced 40% memory requirement.

Full textAbstract:
碩士<br>國立交通大學<br>電子工程系<br>89<br>With the increasing demand for digital media, there has been significant interest in the deployment of image and video communication services. As communication channels are limited in bandwidth, compression techniques are employed to reduce the amount of information to be transmitted. While the bit rate reduction is achieved, a strong data dependency is created. When the channel deteriorates because of noise, interference, and so on, the picture quality can suffer abruptly. Much effort has been invested in R&D to build error resilience into the compressed bit-stream and ensure improving the quality of image/video transmission in noisy or error-prone environment.
We propose our proposed Bit-Plane EREC. The average compressed rate is 5% less than JPEG standard with the same image quality (PSNR). We also simulated our algorithm at different BERs, and we find that even at high BER of 0.1%, it can still achieve high image quality (PSNR = 26dB). Besides, we compare our algorithm with EREC [24]. We find that our performance higher than EREC [24], however our algorithm complexity is lower than it.
Our Bit-Plane EREC image codec can compress and decompress CIF size (352 x 288)(format：4:2:0) images at the rate of 30 frames per second at clock rate 20MHz. The EREC image codec has been fabricated in TSMC 0.35μm 1P4M CMOS technology. The chip integrates 43k gates and occupies a silicon area of 2.95 x 2.95 mm2. The post-layout simulation shows that our chip can operate with clock rate up to 125 MHz at 3.3V power supply. Besides, at clock rate 100MHz the power consumption is 0.255W and 0.222W for encoding and decoding, respectively.

Full textAbstract:
Graph cuts have emerged as an important combinatorial optimization tool for many problems in vision. Most of the computer vision problems are discrete labeling problems. For example, in stereopsis, labels represent disparity and in image restoration, labels correspond to image intensities. Finding a good labeling involves optimization of an Energy Function. In computer vision, energy functions for discrete labeling problems can be elegantly formulated through Markov Random Field (MRF) based modeling and graph cut algorithms have been found to efficiently optimize wide class of such energy functions.
The main contribution of this thesis lies in developing an efficient combinatorial optimization algorithm which can be applied to a wide class of energy functions. Generally, graph cut algorithms deal sequentially with each label in the labeling problem at hand. The time complexity of these algorithms increases linearly with number of labels. Our algorithm, finds a solution/labeling in logarithmic time complexity without compromising on quality of solution.
In our work, we present an improved Logcut algorithm [24]. Logcut algorithm [24]
deals with finding individual bit values in integer representation of labels. It has logarithmic time complexity, but requires training over data set. Our improved Logcut (Heuristic-Logcut or H-Logcut) algorithm eliminates the need for training and obtains comparable results in respect to original Logcut algorithm.
Original Logcut algorithm cannot be initialized by a known labeling. We present a
new algorithm, Sequential Bit Plane Correction (SBPC) which overcomes this drawback of Logcut algorithm. SBPC algorithm starts from a known labeling and individually corrects each bit of a label. This algorithm too has logarithmic time complexity. SBPC in combination with H-Logcut algorithm, further improves rate of convergence and quality of results.
Finally, a hierarchical approach to graph cut optimization is used to further improve on rate of convergence of our algorithm. Generally, in a hierarchical approach first, a solution at coarser level is computed and then its result is used to initialize algorithm at a finer level. Here we have presented a novel way of initializing the algorithm at finer level through fusion move [25]. The SBPC and H-Logcut algorithms are extended to accommodate for hierarchical approach. It is found that this approach drastically improves the rate of convergence and attains a very low energy labeling.
The effectiveness of our approach is demonstrated on stereopsis. It is found that the algorithm significantly out performs all existing algorithms in terms of quality of solution as well as rate of convergence.
