M.Sc. (Computer Science) / In this dissertation, a study of the field of computer vision as well as various fields relating to computer vision is made. An investigation of organic vision is made involving the study of the organic focusing device and visual cortex in humans. This is also done from a psychological point-of-view. Various network models emulating the neuronic networks as well as component networks of the human visual cortex are investigated. Recent work done in the area of neural networks and computer vision is also mentioned. The mathematical theory and techniques used in the area of image formation and image processing, is studied. The study of the field of artificial intelligence and its relation towards the computer vision problem, is made as well as a discussion of numerous application systems that have been developed. Existing industrial applications of computer vision are studied as well as the mentioning of systems that have been developed for this purpose. The use of parallel architectures and multiresolution systems for computer vision application, are investigated. Finally, a discussion of the formal language theory and automata is given in terms of its relevance to computer vision. The discussion centers around the the recognition of two and three-dimensional structures by various automata in the two dimensions. From this study, a formal model for the recognition of three-dimensional digital structures, is proposed and informally defined. It will be the aim of further study to fully develop and implement this model.

A new form of parallelism, distributed bit-parallelism, is introduced. A distributed bit-parallel organization distributes each bit of a data item to a different processor. Bit-parallelism allows computation that is sub-linear with word size for such operations as integer addition, arithmetic shifts, and data moves. The implications of bit-parallelism for system architecture are analyzed. An implementation of a bit-parallel architecture based on a mesh with bypass network is presented. The performance of bit-parallel algorithms on this architecture is analyzed and found to be several times faster than bit-serial algorithms. The application of the architecture to low level vision algorithms is discussed. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate

The past decade has seen a growing interest in computer stereo vision: the recovery of the depth map of a scene from two-dimensional images. The main problem of computer stereo is in establishing correspondence between features or regions in two or more images. This is referred to as the correspondence problem. One way to reduce the difficulty of the above problem is to constrain the camera modeling. Conventional stereo systems use two or more cameras, which are positioned in space at a uniform distance from the scene. These systems use epipolar geometry for their camera modeling, in order to curb the search space to be one-dimensional - along epipolar lines. Following Jain's approach, this thesis exploits a non-conventional camera modeling: the cameras are positioned in space one behind the other, such that their optical axes are collinear (hence the name coaxial stereo), and their distance apart is known. This approach complies with a simple case of epipolar geometry which further reduces the magnitude of the correspondence problem. The displacement of the projection of a stationary point occurs along a radial line, and depends only on its spatial depth and the distance between the cameras. Thus, to simplify (significantly) the recovery of depth from disparity, complex logarithmic mapping is applied to the original images. The logarithmic part of the transformation introduces great distortion to the image's resolution. Therefore, to minimize this distortion, it is applied to the features used in the matching process. The search for matching features is conducted along radial lines. Following Mokhtarian and Mackworth's approach, a scale-space image is constructed for each radial line by smoothing its intensity profile with a Gaussian filter, and finding zero-crossings in the second derivative at varying scale levels. Scale-space images of corresponding radial lines are then matched, based on a modified uniform cost algorithm. The matching algorithm is written with generality in mind. As a consequence, it can be easily adopted to other stereoscopic systems. Some new results on the structure of scale-space images of one dimensional functions are presented. / Science, Faculty of / Computer Science, Department of / Graduate
