In this paper, we propose a progressive compression algorithm for three-dimensional (3-D) mesh data, which can efficiently encode the connectivity and geometry information. Using cosine index predictor and ver-tex confinement rule, the proposed scheme encodes the connectivity information compactly. For the geometry information coding, a 2-stage geometry(More)
We present a multiple description coding (MDC) scheme for 3-D plane-based surfaces. First, planes are split into two disjoint subsets, called descriptions, each of which provides an equal contribution in 3-D surface reconstruction. To optimize the quality of the decoded surface, planes in each description are adaptively compressed according to the channel(More)
