Abstract:

<p>Face detection is a preprocessing step for face recognition algorithms. It is the localization of face/faces in an image or image sequence. Once the face(s) are localized, other computer vision algorithms such as face recognition, image compression, camera auto focusing etc are </p><p>applied. Because of the multiple usage areas, there are many research efforts in face processing. Face detection is a challenging computer vision problem because of lighting conditions, a high degree of variability in size, shape, background, color, etc. To build fully

Abstract:

Inspection of solder joints has been a critical process in the electronic manufacturing industry to reduce manufacturing cost, improve yield, and ensure product quality and reliability. The solder joint inspection problem is more challenging than many other visual inspections because of the variability in the appearance of solder joints. Although many research works and various techniques have been developed to classify defect in solder joints, these methods have complex systems of illumination for image acquisition and complicated classification algorithms.

Abstract:

A new two-dimensional transform is derived and implemented that is able to discriminate with respect to angular and radial frequency. This octave-band directional filter bank (OBDFB) is maximally decimated, has a separable polyphase implmentation, provides perfect reconstruction, and can be implemented in a tree structure allowing for a somewhat arbitrary number of angular and radial divisions. This decomposition is based on the directional filter bank (DFB) and is compared to other transforms with similar properties. Additionally, the OBDFB is used in three applications. Texture segmentat

Visualization, processing and editing of audio, directly on a time-frequency surface, is the scope of this thesis.

Reconstruction properties, scalogram design and enhancements as well audio manipulation algorithms are investigated for this audio representation.The scalogram is designed to allow a flexible choice of time-frequency ratio, while maintaining high quality reco

Abstract:

Inverse problems are ubiquitous in the field of medical imaging and image processing. Prominent examples include image reconstruction and image denoising. The goal of these problems is to reconstruct or restore an unknown image from a set of direct/indirect measurements. However, due to the limitation of the acquisition time or the existence of noise, the obtained measurements are often corrupted or incomplete, which introduces big challenges for the reconstruction process. In order to remove the noise or overcome the ill-posed nature caused by the insufficient measurements, it is necessary to

Stages in Drosophila development denote the time after fertilization at which certain specific events occur in the developmental cycle. Stage information of a host embryo, as well as spatial information of a gene expression region is indispensable input for the discovery of the pattern of gene-gene interaction. Manual labeling of stages is becoming a bottleneck under the circumstance of high throughput embryo images. Automatic recognition based on the appearances of embryos is becoming a more desirable scheme. This problem, however, is very challenging due to severe variations of illumination

For exterior features of cabbage, use Gabor Filters to calculate directions of cabbage and use Sobel Operator Filter to enhance the edges, and use FFT method to get last results. For colors of cabbag

Abstract:

碩士<br>國立臺灣大學<br>資訊網路與多媒體研究所<br>98<br>In the past ten years, face recognition has become a popular area in computer vision. This technique can be used in several applications, such as security system or photo categorization system. Although many technical papers and commercial systems have emerged, recognition of photos under uncontrolled environment is still a challenge. Here we will focus on recognizing different people in home photo datasets without any training procedure. Since Gabor filter has the multi-resolution and multi-orientation characteristics, we implement two algorithms, called L

Abstract:

碩士<br>國立成功大學<br>電腦與通信工程研究所<br>102<br>In traditional stereo matching method, global method is more accurate but spending more time, and have more correct rate in occlusion area. On the contrary, local method is usually fast but have bad performance, and easily is influence by noise. This paper proposed a novel method to compute disparity between two images. It is based on local method, but its cost be aggregated in like-global way. This aggregation is processed by a weight map which created by bilateral filter concept. Every pixel transfer its own cost information to all pixels on the same obje

Abstract:

Face recognition has become a popular area of research in computer vision and one of the most successful applications of image analysis and understanding. We always have to extract optimal features from images to recognize an image as to achieve high accuracy as well as to be efficient. In this thesis an efficient and optimized face recognition algorithm based on Extended Species Abundance Model of Biogeography is presented. We have used Principal Component Analysis (PCA) for the face recognition technique to extract the most important features of the image as all the features, that cons

Abstract:

The analysis and identification of texture is a key area in image processing and computer vision. One of the most prominent texture analysis algorithms is the Gabor Filter. These filters are used by convolving an image with a family of self similar filters or wavelets through the selection of a suitable number of scales and orientations, which are responsible for aiding in the identification of textures of differing coarseness and directions respectively. While extensively used in a variety of applications, including, biometrics such as iris and facial recognition, their effectiveness depend l

Abstract:

Hand Gesture Recognition (HGR) systems are paying more attention in the present scenario due to a wide range of application in real life. These systems are based on the processing of an incoming digital image. In this thesis, the first task is to separate the hand from rest of the image. This can be achieved in several ways and depends on whether the image includes only a hand against a background or the entire person. All the techniques proposed have some limitations. Their performance is affected by the illumination or lighting conditions and complex backgrounds of the hand images. To overco

Abstract:

A document image, beside text, may contain pictures, graphs, signatures, logos, barcodes, hand-drawn sketches and/or seals. Further, the text blocks in an image may be in Manhattan or any complex layout. Document Layout Analysis is an important preprocessing step before subjecting any such image to OCR. Here, the image with complex layout and content is segmented into its constituent components. For many present day applications, separating the text from the non-text blocks is sufficient. This enables the conversion of the text elements present in the image to their corresponding editable form
