Abstract:

As the need for digital libraries, especially genealogical libraries, continues to rise, the need for efficient document image compression is becoming more and more apparent. In addition, because many digital library users access them from dial-up Internet connections, efficient strategies for compression and progressive transmission become essential to facilitate browsing operations. To meet this need, we developed a novel method for representing document images in a parametric form. Like other “hybrid" image compression operations, the Contour Encoded Compression and Transmission (CECAT) sys

Abstract:

The time to detection of a visual stimulus by the primate eye is recorded at 100 – 150ms. This near instantaneous recognition is in spite of the considerable processing required by the several stages of the visual pathway to recognise and react to a visual scene. How this is achieved is still a matter of speculation. Rank-order codes have been proposed as a means of encoding by the primate eye in the rapid transmission of the initial burst of information from the sensory neurons to the brain. We study the efficiency of rank-order codes in encoding perceptually-important information in an image

Abstract:

In cell populations there is a great deal of heterogeneity. Cells can be seen to react different to the same stimulus despite being the same cell type and under the same conditions. Single cell analysis of a population is, therefore, crucial to understanding the nature of these differences. Using different technologies to study a single cell can help a researcher gather more data on the nature of these differences. The first part of this study looked at the development of a microwell array as a technique to allow correlative microscopy of non-adherent cell types. Laser ablation was used to gen

In this thesis we focus on two diﬀerent image processing challenges: high dynamic range (HDR) image/video generation, and colour matching. In both cases, we redeﬁne these tasks by taking into account the prior knowledge from the diﬀerent processes the camera performs when capturing the image. High dynamic range techniques have recently become very popular, thanks to the emergence of HDR recording and displaying technology. We propose two diﬀerent approaches for HDR creation, one for still images, and one for video creation. In case of still images, most of previous methods follow a multiple ex

Abstract:

Due to the high correlation of neighbouring pixel values of a digital image, DPCM picture transmission has been a well investigated area of image compression. DPCM has found its way into standards such as JPEG and MPEG which have revolutionized the multimedia industry. However, because of the high noise sensitivity of DPCM compressed images, techniques must be developed to reduce the disturbing effects of channel errors. Hence, a DPCM image transmission system over a binary symmetric channel is studied, along with techniques used to improve picture quality. Two concepts which are the foc

博士<br>國立成功大學<br>電機工程學系碩博士班<br>98<br>H.264, MPEG-4 Part 10, is the latest digital video coding standard that achieves very high data compression by using several new coding features. In H.264/AVC intra frame coding, the rate-distortion optimization (RDO) is employed to select the optimal coding mode to achieve the minimum rate-distortion cost. Due to a large number of combinations of coding modes, the computational burden of intra prediction becomes extremely high for real time applications. This dissertation aims to propose fast algorithms for intra coding to enhance the coding speed while ret

Abstract:

碩士<br>中原大學<br>電子工程研究所<br>102<br>In this thesis, a low-cost and low-complexity lossless image compression algorithm based on JPEG-LS is proposed for the implementation of wireless capsule endoscopy. Since the proposed algorithm is developed for VLSI implementation, a context model in traditional JPEG-LS standard is reduced because of the high complexity and memory requirement. The proposed novel low-complexity lossless image compression algorithm contains a prediction model, a regular mode, and a hybrid entropy coding model. The hybrid entropy coding model consists of a Huffman and a Golomb-Ric

博士<br>國立臺灣科技大學<br>電子工程系<br>104<br>Based on the embedded zero tree (EZT) coding with discrete wavelet transform (DWT), SPIHT (set partitioning in hierarchical trees) is a highly efficient image compression technique that can be stopped at any bit, and thus allows for progressive transmission. However, one problem exist- ing in SPIHT is that its decoding could be extremely sensitive to bit errors in the code sequence. In this dissertation, we address the issue of trans- mitting SPIHT-encoded images via noisy channels, wherein errors are inevitable. The communication scenario assumed in this dis

Abstract:

Abstract In recent years, deep neural networks have achieved extraordinary performance on supervised learning tasks. Convolutional neural networks (CNN) have vastly improved the state of the art for most computer vision tasks including object recognition and segmentation. However, their success relies on the presence of a large amount of labeled data. In contrast, relatively fewer work has been done in deep learning to handle scenarios when access to ground truth is limited, partial or completely absent. In this thesis, we propose models to handle challenging problems with limited labeled inf

Abstract:

The purpose of this research is to study the detection of temporal changes between two (or more) multimodal images satellites, i.e., between two different imaging modalities acquired by two heterogeneous sensors, giving for the same scene two images encoded differently and depending on the nature of the sensor used for each acquisition. The two (or multiple) multimodal satellite images are acquired and coregistered at two different dates, usually before and after an event. In this study, we propose new models belonging to different categories of multimodal change detection in remote sen
