MATLAB-CALIC

EZW matlab 源码用于图像压缩试验()

随机解调器，可在压缩感知中获取压缩采样。(Get compressed samples)

newmark-b法的简要程序，供大家使用(newmark-b)

A Visual Cryptography Based Watermark Technology for Individual

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

哈夫曼编码译码系统，设置发送者和接受者两个功能， 发送者的功能包括： ①输入待传送的字符信息； ②统计字符信息中出现的字符种类数和各字符出现的次数（频率）； ②根据字符的种类数和各自出现的次数建立哈夫曼树； ③利用以上哈夫曼树求出各字符的哈夫曼编码； ④将字符信息转换成对应的编码信息进行传送。 接受者的功能包括： ①接收发送者传送来的编码信息； ②利用上述哈夫曼树对编码信息进行翻译，即将编码信息还原成发送前的字符信息。 (Huffman decoding system, set the sender and the recipient of two functions, the sender' s features include: (1) input to be transmitted character information ② statistical character information, the number of types of characters and characters the number of occurrences (frequency create a Huffman tree) ② According to the number of types of characters and their respective number of occurrences ③ use the Huffman tree to find the characters Huffman coding ④ character information into the corresponding coding information for delivery. The recipient of the features include: (1) to receive the coded information to the sender transmission ② above Huffman tree coded information to be translated, is about to coded information to restore the character information before sending.)

实现对图像的lzw压缩编码 得到图像的压缩比以及码长(Lzw realize image compression coding of image compression ratio as well as the code length)

说明：  JPEG-LS压缩和解压缩算法的C代。。。。(This is a commonly used JPEG-LS codec C language.)

赫夫曼编/译码器源码，已生成的每个字符的赫夫曼编码，对任意字符文本进行编码，再译码(Huffman encoder/decoder source code, Huffman coding, each character has been generated, the text of any character encoding, decoding)

JPEG编码和解码，用Huffman编码(JPEG encoding and decoding, using Huffman coding)
