This work aims at determining dense motion and disparity fields given a stereoscopic sequence of images for the construction of stereo interpolated images. At each time instant the two dense motion fields, for the left and the right sequences, and the disparity field of the next stereoscopic pari are jointly estimated. The disparity field of the current stereoscopic pair is considered as known. The disparity field of the first stereoscopic pair is estimated separately. For both problems multi-scale iterative relaxation algorithms are used. Stereo occlusions and motion occlusions/disclosures are detected using error confidence measures. For the reconstruction of intermediate views a disparity compensated linear interpolation algorithm is used. Results are given for real stereoscopic data.
