AES压缩技术编程源代码,包含压缩和解压全套源代码的完整工程(AES compression technology programming source code, including compression and decompression full source code of complete project )

Codes". Huffman coding uses a specific method for choosing the representation for each symbol, resulting in a prefix code (sometimes called "prefix-free codes") (that is, the bit string representing some particular symbol is never a prefix of the bit string representing any other symbol) that expresses the most common characters using shorter strings of bits than are used for less common source symbols. Huffman was able to design the most efficient compression method of this type: no other mapping of individual source symbols to unique strings of bits will produce a smaller average output size when the actual symbol frequencies agree with those used to create the code. A method was later found to do this in linear time if input probabilities (also known as weights) are sorted.

RLE是一个压缩的算法，里面有算法的C++程序实现。(RLE is a compression algorithm, there are algorithms C++ program)

算术编码，利用算术编码进行数据压缩，用C语言实现，程序简单，已跑通(Arithmetic coding, the use of arithmetic coding for data compression, using C language, the procedure is simple, has run through)

非常好的视频压缩filter,可以实现mpeg2 mpeg1的视频压缩，用户可以自己选择码率(very good video compression filter can achieve mpeg1 mpeg2 video compression, Users can choose Rate)

压缩的所有文件,解压缩的所有文件(zip unzip)

基于verilog的LZS压缩和解压算法，压缩比1；2 。里面带有C原言的代码。已经通过验证！(Verilog based LZS compression and decompression algorithm, compression ratio 1; 2. It has the C code in it. It has been verified!)

Many crc routine in C

说明：  JPEG压缩，matlab实现的JPEG压缩算法(JPEG compression, matlab code)
