Matlab的数理统计工具箱是Matlab工具箱中较为简单的一个,其牵扯的数学知识是大家都很熟悉的数理统计,因此在本文中,我们将不再对数理统计的知识进行重复,仅仅列出数理统计工具箱的一些函数,这些函数的意义都很明确,使用也很简单,为了进一步简明,本文也仅仅给出了函数的名称,没有列出函数的参数以及使用方法,大家只需简单的在Matlab工作空间中输入“help 函数名”,便可以得到这些函数详细的使用方法。(Mathematical Statistics Toolbox Matlab Matlab toolbox is a relatively simple one, it involves mathematical knowledge is the number of people are familiar with statistics, so in this article, we will no longer be on the knowledge of mathematical statistics to repeat, only lists Mathematical Statistics Toolbox functions that the meaning of these functions are very clear, very simple to use, in order to further condensed, this article only gives the name of the function, the parameters of the function is not listed, and the use of methods, we simply Enter the workspace in the Matlab " help function name" , it can be to use these functions in detail.)

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。

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.
