Description: 有两个vc工程文件，分别是lzc编码和解码。算法主要可以对灰度图像进行压缩和解压缩，效果比jpeg要好。其实这就是jpeg2000的原型。-two vc engineering documents were lzc encoding and decoding. This algorithm can be gray image compression, the effect is better than jpeg. This is actually the prototype JPEG2000.

Description: 数字图像处理实验
根据原图像的直方图，发现背景和目标的分割值大约在130左右，并将灰度图像转为二值图像，分割效果比较理想。
图像处理实验（六）图像压缩与编码
实验目的： 学习JPEG压缩编码
实验内容：
一．实现基本JPEG的压缩和编码分三个步骤：
1． 首先通过DCT变换去除数据冗余；
2． 使用量化表对DCT系数进行量化；
3． 对量化后的系数进行Huffman编码。-digital image processing experiments based on the original image histogram, found background and objectives of the divided about the value of around 130 and two gray-scale image to image, Segmentation more satisfactory results. Image processing experiments (6) Image Compression and Coding of the experiment : Learning JPEG compression coding experiment : one. Basically JPEG compression and coding in three steps : 1. First through DCT remove data redundancy; 2. Using quantitative table right DCT coefficient quantization; 3. Right quantized coefficients of Huffman coding.

Description: DCT变换是数字图像处理中重要的变换，很多重要的图像算法、图像应用都是基于DCT变换的，如JPEG图像编码方式。对于大尺寸的二维数值矩阵，倘若采用普通的DCT变换来进行，其所花费的时间将是让人难以忍受甚至无法达到实用。而要克服这一难点，DCT变换的快速算法无非是非常吸引人的-DCT digital image processing is an important transformation, many important images algorithm, imaging applications are based on the DCT, such as JPEG image encoding. For large-size two-dimensional numerical matrix, if only the ordinary for DCT, they spent the time people will be unable to reach intolerable even practical. To overcome this difficulty, DCT fast algorithm is nothing more than a very attractive

Description: This file contains a new and improved version of the Huffman coder, (June 29. 2001). The name is Huff06.m. There are also some additional files which are helpful when using Matlab for data compression: quantizer, different variants of run-length-encoding and end-of-block coding in Mat2Vec, and a program which do JPEG-like entropy coding. A complete compression example is shown in TestMat2Vec.m. This file is all you need for Huffman coding in MatLab.-This file contains a new and improved version of on of the Huffman coder, (June 29. 2001). The name is Huff06.m.
