用matlab实现的霍夫曼编码的图像压缩，主要就是依据霍夫曼编码的原理实现的图形图像处理。(Using the Huffman code matlab realize the image compression, Huffman coding is mainly based on the principle realize graphics image processing.)

直方图的计算与显示分析图像、物体和视频信息过程，我们常把看到的物体用直方图（histogram）表示，直方图可以用来描述各种不同的事情，如物体的色彩分布、物体边缘梯度模板，以及表示目标位置的概率分布(Calculation and analysis of the histogram display images, objects and video information process, we often see objects with the histogram (histogram) indicates, the histogram can be used to describe a variety of different things, such as the color distribution of objects, object edges gradient templates, and the probability distribution of the target position)

本算法一种基于量子遗传算法的图像增强方法，包含多个m子文件。使用量子旋转门(The algorithm based on quantum genetic algorithm of image enhancement methods, contains more than one m subfolders. The use of quantum revolving door)

李纯明博士的无需初始化模型的源代码，作者亲自写的。还有测试图象，相信对大家肯定有好处。(Economics Dr. initialization model without the source code, written by the author himself. There test image, I think we will benefit.)

通过直线拟合进行钻石角度的测量，包括二值化，边缘检测，直线拟合最后进行数学算法进行角度测量(Measurement of Diamond Angle by Linear Fitting)

说明：  运用低通滤波器，中心削波和自相关技术估计一段男性和女性语音信号的基音周期，画出基音轨迹曲线，给出估计准确率。(The use of low-pass filter, the center clipping and related technologies is estimated from a male and female speech signal pitch period, pitch trajectory drawn curves of estimated accuracy.)

对普通的粒子滤波和一种改进的粒子滤波算法进行比较，证明改进算法优越性(Of ordinary particle filter and an improved particle filter for comparison, to prove the superiority of improved algorithm)

这是用matlab编写的图像缩放代码，能实现灰度或者彩色图像的放大缩小以及小数倍。使图像处理初学者的好材料(This is used to prepare the image scaling matlab code, to achieve gray scale or color images and small many times zoom. Image processing to make a good material for beginners)

说明：  采用matlab实现高斯金字塔，函数Gscale(img,levels,gsize,sigma)(To achieve Gaussian pyramid using matlab)

图像的嵌入与提取：VC++中在一个图像A中嵌入一图像B，并能把图像B提取出来。(Image embedding and extraction: VC++ in an image embedded in an image A, B, and B images can be extracted.)
