In Huffman coding, fixed-length blocks of the source symbols are mapped onto variable-length binary blocks. Huffman code is a prefix-free code, which can thus be decoded instantaneously and uniquely. Huffman codes are formulated to be an optimal code, i.e., they achieve the shortest average ...
adaptive Huffman coding is designed to compress the generated labels in order to reduce the embedding length of the auxiliary information used for the extraction and recovery. Experiments show that the proposed method with MED+GAP predictor and adaptive Huffman coding improves 0.052 bpp, 0.023 bpp, ...
Vector quantization (VQ) is an effective and important compression technique with high compression efficiency and widely used in many multimedia applications. VQ compression is a fixed-length algorithm for image block coding. In this paper, we employ the Huffman Coding technology to enhance VQ ...

refers to the use of a variable-length code table for encoding a source symbol where the variable-length code table has been derived based on the estimated probability of each possibly value of the source symbol. Huffman coding is currently used as compression method for multimedia coding, such...
