About the Edition

This thesis presents the design and implementation of a multi-resolution graph cuts (MRGC) for stereo-motion framework that produces dense disparity maps. Both stereo and motion are estimated simultaneously under the original graph cuts framework [8]. Our framework extends the problem from one to five dimensions, creating a large increase in complexity. Using three different multi-resolution graph cut algorithms, LDNR, EL and SAC, we reduce the number of pixels m and the number of labels n that limit the alpha -- beta swap algorithm (with complexity O(mn2) required from the definition of our semi-metric smoothness function. This results in a reduction of computation time and the ability to handle larger images and larger label sets. The choice of the three MRGC algorithms to use in computation determines the appropriate level of accuracy and computation time desired.

The multiview video coding (MVC) extension of H/MPEG-4 AVC is one of the most promising visual encoders for three-dimensional television and free viewpoint video applications. In this paper, we propose a joint dense motion/disparity estimation algorithm, designed to replace the classical temporal/inter-view unit within MVC, which uses a block-based motion/disparity by: lem involves the estimation of four dense fields: two motion fields and two disparity fields.

In order to reduce computational complex-ity and improve estimation accuracy, the two motion fields, for the left and right sequences, and the disparity field of the current stereo pair are jointly estimated, using the stereo-motion consistency Cited by: 7.

Foreword by Anil K. Jain The objective of mathematical modeling in image processing and computer vision is to capture the intrinsic character of the image in a few parame-ters so.

Example-based methods are effective for parameter estimation problems when the underlying system is simple or the dimensionality of the input is low.

For complex and high-dimensional problems such as pose estimation, the number of required examples and the computational complexity rapidly becme prohibitively high.

Although the coupled estimation of contours and pose parameters is beneficial compared to the uncoupled case, segmentation results can be inaccurate, as.
