- 这个程序主要是对图像进行huffman编码，从实现了对图像的压缩编码。,This program huffman coding image from image coding.
Huffman
- Huffman编码的主导思想是根据数据符号发生的概率进行编码。在源数据中出现概率越高的符号，相应的码长越短；出现概率越小的符号，其码长越长，从而达到用尽可能少的码符号表示源数据。Huffman编码方法是接近压缩比上限的一种最佳的编码方法。-The dominant idea of the Huffman coding is based on the probability of occurrence of data symbols for encoding.The higher the prob
