说明：  直方图匹配，或者叫做直方图规定化。在matlab下实现，但是没有使用IPT中的histeq进行规定化。(Histogram matching,or histogram specification is the basic method in the digit image processing. We provide a implementation in matlab without using IPT function histeq)

用matlab写的人脸检测代码,具有很好的识别率，对做人脸识别，检测的研究有一定的帮助(the code is used to face detaction and it has a high rate.It is very useful for the search of face detaction )

此文件一共包含3个m文件。第一个文件的功能是绘制一个二值图像，并显示其傅立叶幅度谱。文件2功能是设计频域理想低通滤波器，并加以验证：读入一个二值图像(cameraman.tif)加噪声后在频域进行低通滤波观察滤波后的图像效果。文件3的功能是对图像eight.tif加入椒盐噪声后，实现Butterworth低通滤波.(This file contains 3 m documents. Functions of first file is to draw a binary image, and displays its Fourier amplitude spectrum. Document 2 is designed to function a frequency domain ideal low-pass filter , and verified it: reading a binary image (cameraman.tif) plus noise on it and smoothing it in the frequency domain using low-pass filtering.The filtered effect will be observed by displaying image.Document 3 is designed to read a binary image(eight.tif) and add salt and pepper noise on it, realized frequence domain Butterworth low-pass filter.)

实现人脸识别及分割，使用人脸进行RGB颜色提取，并分层提取特征信息。(Realize face recognition and segmentation, use face for RGB color extraction, and extract feature information hierarchically.)

粒子滤波跟踪，还算不错的一个demo，调试验证可以通过(Particle filter tracking, fairly good one demo, debug and verify through)

消除波面倾斜的函数，可以用于将波面的倾斜消去(Elimination wavefront tilt function, can be used to eliminate the inclined wavefront)

N年前上数字图像课时写的实验报告和程序，用滤波反投影（Filter Back Project，FBP)法重建图像。(Report and source code for data image restore experiment, using FBP.)

压缩感知去噪代码，一种用于去噪的CS的有效代码，简单适用(Compressed sensing denoising code, one for denoising CS valid code, a simple application )
