Abstract
Source coding of multi-view image sequences is investigated. Two different frameworks are considered. The first one is a bidirectional predictive coding scheme, in which the displayed frames can be instantaneously decoded given the coded furthest right and left images. The second one is a unidirectional predictive coding scheme, in which the central frame is an I-frame and the remaining frames are coded based on this frame. Both frameworks can overcome problems related to occlusion, are compatible with current and proposed image and video coding standards, consider the special indexing characteristics of multi-view sequences, and can be implemented in applications where the display device has a small buffer. The actual coding is performed using the subspace projection technique, a locally adaptive transform approach. The transformation matrix is equivalent to a projection operation and is determined using the local cross-correlation characteristics. Several design issues in generating the adaptive transforms and experimental results are presented.
