Abstract:

Stereo vision from short-baseline image pairs is one of the most active research fields in computer vision. The estimation of dense disparity maps from stereo image pairs is still a challenging task and there is further space for improving accuracy, minimizing the computational cost and handling more efficiently outliers, low-textured areas, repeated textures, disparity discontinuities and light variations. This PhD thesis presents two novel methodologies relating to stereo vision from short-baseline image pairs: I. The first methodology combines three different cost metrics, defined using col

Abstract:

Computer stereo vision technique has been prevalently used in various automotive applications for depth perception. This thesis mainly focuses on developing a computationally efficient and highly accurate disparity estimation algorithm for three automotive applications, i.e., lane detection, road surface 3-D reconstruction and pothole detection. Firstly, the real-time implementation of an efficient stereo matching algorithm is proposed to acquire dense disparity maps for road scenes, where the disparities are estimated iteratively whereby the search range on each row is propagated from three e

Abstract:

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

Abstract:

3D face modeling is currently a popular area in Computer Graphics and Computer Vision. Many techniques have been introduced for this purpose, such as using one or more cameras, 3D scanners, and many other systems of sophisticated hardware with related software. But the main goal is to find a good balance between visual reality and the cost of the system. In this thesis, reconstruction of a 3D human face from a pair of stereo cameras is studied. Unlike many other systems, facial feature points are obtained automatically from two photographs with the help of a dot pattern projected on the object

A significant amount of research in the field of stereo vision has been published in the past decade. Considerable progress has been made in improving accuracy of results as well as achieving real-time performance in obtaining those results. Although much of the literature does not address it, many applications are sensitive to the tradeoff between accuracy and speed that exists among stereo vision algorithms. Overall, this work aims to organize existing efforts and encourage new ones in the development of stereo vision algorithms for resource limited systems. It does this through a review of

Photometric stereo is a method of estimating surface geometry by using a fixed-position camera and multiple light sources. The idea of photometric stereo is to vary the direction of incident illumination between successive images, while the viewing direction is constant; in this way, the correspondence of image points is known beforehand, as the position of the object is not changed, and surface orientation is determined by using the radiance values recorded with the different images. Photometric stereo has several applications: it is used to detect small surface defects, imperceptible to the
