说明：  通过matlab，可以快速得到图像的特定区域的灰度值，里面也有一些解释(Through MATLAB, we can quickly get the gray value of the specific region of the image, which also has some explanations)

用SIFT结合光流场进行图像配准，得到不错的效果(The image registration is carried out with SIFT combined with optical flow field, and good results are obtained.)

这个matlab程序实现图像的任意角度的顺时针旋转。(The matlab program images at any angle of clockwise rotation.)

基于混沌理论的Logistic映射数字图像的加密算法，实现图像的置乱(Based on the Chaos Theory of Logistic mapping digital image encryption algorithm, the realization of image scrambling)

基于卡尔曼滤波器的监控系统的设计，实现了对运动目标进行识别，并对其运动轨迹进行预测的功能；当二值化图像超过一定阈值时，判断为有外人入侵，实现报警功能。(Kalman filter based on the design of monitoring system to achieve the recognition of moving objects, and its motion trajectory prediction function when the binary image exceeds a certain threshold, to determine the invasion of outsiders, to achieve alarm function.)

自己用matlab写的灰度图像压缩解压程序 jpegencoder可以打开图像压缩后存储为c.jpg（只限于灰度图像） jpegdecoder只适用于把jpegencoder的c.jpg解压，还不可以对任意图像解压，有待以后完善 作者 ar_dong(jpegencoder jpegdecoder author ar_dong)

说明：  模式识别-贝叶斯最小错误率判别一幅图像是属于人，还是属于背景。图像经过预处理。(pattern recognition- Bayesian smallest error rate discriminant image is a person, or belong to the background. After pretreatment images.)

将图片由RGB格式转化为YCbCr格式下，用椭圆方法判定肤色和非肤色区域，进行二值化处理，最后显示结果(Pictures from RGB format into a YCbCr format, the method used to determine color elliptical and non-color regions, to carry out binarization processing, the final result will be displayed)

随机过程实验（研一）包含的程序：离散时间马尔可夫链、连续时间马尔科夫链、布朗运动。(Random process experiments (yanyi) program included: discrete time Markov chains, continuous-time Markov chains, Brownian motion.)

有关数字图像处理的一些源码，可以实现一些处理图像的功能，但要配合数字摄像机使用(Digital image processing of the number of source, you can achieve the functions of image processing, but with the use of digital cameras)
