摘　要 文章以空间监控系统为背景,深入研究了JPEG图像压缩标准的实现方法,并基于FPGA对其进行了实现和优化。文中给出了详细的实现方法和优化过程,测试表明达到了很好的效果。 简单介绍了有损静态图像压缩当前有两种比较流行的标准JPEG和JPEG2000。说明了用JPEG方法压缩的原因。 介绍JPEG基本原理：JPEG对灰度图像的压缩处理过程主要包括:图像分割,离散余弦变换(DCT),量化(Quantization),“Z”形排序(Zigzag Scan),差分脉冲编码调制(Differential Pulse Code Modulation,DPCM)对直流系数(DC),行程长度编码(Run-Length Encoding,RLE)对交流系数(AC),霍夫曼(Huffman)编码等。 JPEG标准的特点是离散余弦变换。 比较详细介绍压缩系统的构成和实现。实现提及步骤， JPEG压缩模块设计和编码模块实现细节。 (Abstract Article in the space monitoring system for the background, in-depth study of the JPEG image compression standard implementation methods and carried out based on FPGA implementation and optimization. In this paper, a detailed method of implementation and optimization of the process, testing showed that to achieve good results. Easy introduction of harmful static image compression has two kinds of comparisons that the current popular standard JPEG and JPEG2000. Illustrated by the reasons for JPEG compression method. JPEG introduce the basic principles: JPEG compression of gray-scale image processing include: image segmentation, discrete cosine transform (DCT), quantization (Quantization), "Z"-shaped sort (Zigzag Scan), differential pulse code modulation (Differential Pulse Code Modulation, DPCM) on the DC coefficient (DC), Run Length Encoding (Run-Length Encoding, RLE) of the exchange coefficient (AC), Hoffman (Huffman) coding. JPEG standard is characterized by discrete )

说明：  用MATLAB实现的数字水印的DCT算法，还包括本次试验的实验报告，对算法有详细的解读！(Implemented using MATLAB DCT digital watermarking algorithm, also including the test lab report, a detailed interpretation of the algorithm!)

Dijkstra通用算法，最近一段时间一直在搞图论的相关算法，发现Dijkstra是一个很好的单元最短路径算法，此程序很短，非常适合学习(Generic Dijkstra algorithm, the most recent period has been engaged in graph theory algorithms, Dijkstra is a good unit the shortest path algorithm, this procedure is very short, very suitable for learning)

这是一个matlab编写的计算人脸识别率的小程序，选选用的图像数据库位ORL数据库。，已通过测试。 (This is a matlab write a small program to calculate the face recognition rate, the election chosen image databases bit ORL database. , Has been tested.)

这个程序再matlab2012b版本上调试成功，以前在毕业设计的时候在网上找到的资料，希望对大家有用，SOM算法,matlab程序,是经典的教科书的例子程序(This program debug version then matlab2012b success in graduate design information previously found on the Internet when we want to be useful, SOM algorithm, matlab program, is a classic textbook example of program)
