In comparison to the previous encoding methods, which use only Huffman or arithmetic coding method to encode operator series, this coding method can efficiently compress connectivity information by first calculating Huffman code for every symbol in connectivity series, followed by encoding the Huffman code through using a context-based arithmetic coding method. Experimental results indicate that this method can be applied to almost all the connectivity compression algorithms for meshes. The compression result by using this entropy encoding method is generally higher than the entropy of the series-the best compression result that most connectivity compression algorithms of mesh can obtain respectively. %K Huffman code %K context-based arithmetic coding %K mesh %K connectivity compression %K encode %K decode
