| Abstract: | The method of Huffman coding that is frequently used in image compression is discussed. A method of finding the Huffman code with the lowest average deviate variance among various Huffman codes is provided, so the accuracy of data transfer is improved and the size of the data buffers during the process of data receiving is reduced. |

| Keywords: | Huffman coding image entropy average code length average deviate variance image gray level |
