- W2291954278 abstract "Efficient compression techniques are required for animated mesh sequences with fixed connectivity and time-varying geometry. In this paper, we propose a key-frame-based technique for three-dimensional dynamic mesh compression. First, key-frames are extracted from the animated sequence. Extracted key-frames are then linearly combined using blending weights to predict the vertex locations of the other frames. These blending weights play a key role in the proposed algorithm because the prediction performance and the required number of key-frames greatly depend on these weights. We present a novel method in order to compute the optimum blending weight that makes it possible to predict location of the vertices of the non-key frames with the minimum number of key-frames. The residual prediction errors are finally quantized and encoded using Huffman coding and another heuristic method. Experimental results on different test sequences with various sizes, topologies, and geometries demonstrate the privileged performance of the proposed method compared with the previous techniques.
