Paper Abstract

Efficient compression techniques for stereoscopic sequences (3DTV) are required for storage and transmission purposes. One general approach for image sequence coding is based on motion compensation schemes. We propose a new method which enables a joined estimation of global motion descriptor vectors both for left and right sequences. The estimation of descriptors in stereoscopic sequences presented in this paper generalizes pel-recursive methods using steepest descent algorithms subject to some constraints of coherence. In the case of parallel estimations (on the left and right views), eight descriptors can characterize the motion of two matched regions. By the coherent estimation detailed here, only five descriptors can represent the motion of two matched regions. Results are evaluated according to reconstruction errors and qualitative interpretation of apparent motion fields.
