Abstract

Off-line scanning, coding, transmission and remote animation of the human affect represents a possible processing pipeline for providing 3D immersion in virtual worlds. In this paper we target applications that make use of compact and scalable 3D representations of human affect and require close control over the local error introduced by lossy coding of the mesh geometry. To satisfy this requirement, we propose a novel L-infinite wavelet-based semi-regular mesh coding system. The system lies in contrast with classical mesh coding approaches which make use of the L-2 distortion metric. Specifically, in contrast to an L-2 driven implementation, the proposed system provides a bound on the local error on each vertex resulting from scalar embedded quantization of the wavelet coefficients. The experiments show that the proposed system provides scalability in L-infinite sense and that it outperforms the state-of-the art in L-infinite mesh coding.
