WebHuffman's greedy algorithm constructs optimal prefix codes called Huffman Codes. It is given a set C of n characters, where each character has frequency c.freq in the "text" to be encoded. The optimality of a code is relative to a "text", which can be what we normally think of as texts, or can be other data encoded as sequences of bits, such as images.

WebTo split the DCT coefficients to Entropy and CS paths, we developed five different algorithms; each algorithm uses a unique method to split every 8×8 block in the image into two parts. First part is encoded using Huffman coding, while the second part goes through compression stage using CS, then encoded using Huffman coding.
