Description: vb jpeg编码这是一个比较完整的JPEG压缩程序，支持 彩色/灰度、Y分量水平/垂直采样律、图像质量 调整。使用的是最简单的基线系统（BaseLine）压缩方式，量化表及Huffman表都是与ACDSee一致的，没有提供自适应Huffman表压缩功能。-vb jpeg coding This is a relatively complete JPEG compression process, support for color/grayscale, Y component level/vertical sampling law, image quality adjustment. The use of the most simple baseline system (BaseLine) compression method to quantify the Huffman table and the table with ACDSee are the same, and did not provide adaptive Huffman compression table.

Description: In each step the LZSS algorithm sends either a character or a <position, length> pair. Among these, perhaps character "e" appears more frequently than "x", and a <position, length> pair of length 3 might be commoner than one of length 18, say. Thus, if we encode the more frequent in fewer bits and the less frequent in more bits, the total length of the encoded text will be diminished. This consideration suggests that we use Huffman or arithmetic coding, preferably of adaptive kind, along with LZSS.-In each step the LZSS algorithm sends either a character or a lt;position, lengthgt; pair.

Description: 来有人提出了一种动态的哈夫曼编码方法。动态哈夫曼编码使用一棵动态变化的哈夫曼树，对第t+1个字符的编码是根据原始数据中前t个字符得到的哈夫曼树来进行的，编码和解码使用相同的初始哈夫曼树，每处理完一个字符，编码和解码使用相同的方法修改哈夫曼树，所以-was raised to a dynamic Huffman coding method. Dynamic Huffman coding using a dynamic changes in the Huffman tree for the first t a character encoding is based on the original data before t characters in the Huffman tree for the encoding and decoding using the same initial Huffman tree, each dealing with a character encoding and decoding using the same side Law Revision Huffman tree.
