The Optimization of Huffman Coding
摘要/Abstract
摘要：
对图像压缩中常用的Huffman编码进行讨论,给出了在多种Huffman编码中寻找平均偏离方差最小的一种编码方法,以提高数据传输的准确率,同时在数据接收中减小数据缓冲器容量.
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 codesis provided, so the accuracy of data transfer is improved and the size of the data buffers during the process of data receiving is reduced.
