Evaluation of multiresolution block matching techniques for motion and disparity estimation

摘要

Multiresolution block matching methods for both monocular and stereoscopic image sequence coding are evaluated. These methods are seen to drastically reduce the amount of processing needed for block correspondence without seriously affecting the quality of the reconstructed images. The evaluation criteria are the prediction error and the speed of the algorithm for motion, disparity, and fused motion and disparity estimation, in comparison with the full search (exhaustive) method. A new method is also proposed based in multiresolution techniques, for efficient coding of the disparity or the displacement vector field.
