SCALABLE COMPRESSION OF TIME-CONSISTEND 3D MESH SEQUENCES

摘要

We present a method for predictive compression of time-consistent 3D mesh sequences supporting and exploiting scalability. The applied method decomposes each frame of a mesh sequence in layers, which provides a time- consistent multi-resolution representation. Following the predictive coding paradigm, local temporal and spatial dependencies between layers and frames are exploited for layer-wise compression. Prediction is performed vertex-wise from coarse to fine layers exploiting the motion of already encoded neighboring vertices for prediction of the current vertex location. Consequently, successive layer- wise decoding allows to reconstruct frames with increasing levels of detail.
