Abstract

We present a model-based approach to encode multiple synchronized
video streams depicting a dynamic scene from different viewpoints.
With approximate 3D scene geometry available, we compensate for
motion as well as disparity by transforming all video images
to object textures prior to compression.
A two-level hierarchical coding strategy is employed to efficiently
exploit inter-texture coherence as well as to ensure quick random
access during decoding.
Experimental validation shows that attainable compression ratios
range up to 50:1 without subsampling.
The proposed coding scheme is intended for use in conjunction with
Free-Viewpoint Video and 3D-TV applications.
