Entropy encoding is used to additional compresses the quantized values losslessly to provide enhanced overall compression. Diverse encoding methods can be used (e.g. Run Length, Huffman, Arithmetic, Shift Coding, and LZW). Statistical based encoding ways are used to eliminate data that are frequently occurring.
