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.
