这份代码是使用haar+adoboost做人脸检测用的，文件中还包括其他的特征选择，特征提取的算法，对于想做人脸检测这一块的朋友，可以下载来研究。(This code is used haar+adoboost human face detection, the document also includes other feature selection, feature extraction algorithm for face detection which one wants a friend, you can download to study.)

YUV420视频的缩放，经过高度的优化，其中三次卷积插值（cubic convolution）算法的效果最好，优化程度也最高。其基本思想是通过整型化、查表等方法消除每一帧图像插值运算中的浮点运算和乘除法运算。(scale YUV420 video frames with cubic, bilinear & cubic convolution interpolation algorithms。)

梯度倒系数滤波,在小目标检测算法中,用来实现背景抑制,提高目标的信噪比.(reversing gradient filter coefficients in small target detection algorithm, which can be used for background suppression, the goal of improving the signal-to-noise ratio.)

该程序通过雅可比矩阵求解Rossler系统的李雅普诺夫指数指数，并绘制了其频谱图。(The program solves the Lyapunov exponent of Rossler system by Jacobian matrix and draws its spectrum.)

说明：  编程实现对bmp图像最大值，最小值，标准差，熵，各灰度值频率的计算(Programming to calculate the maximum value, minimum value, standard deviation, entropy and gray value frequency of BMP image)

图像处理课程设计——《人脸识别》，用matlab实现的，代码加实现，以及设计报告(Image processing designation of face recognize.)

视觉注意机制一种新型的目标检测方法，该文给出了一种比较有效的处理策略(Visual attention mechanism to target a new detection method, the paper gives a more effective treatment strategies)

图片雾化效果 实例

基于otsu的自适应阀值canny边缘检测(adaptive canny edge detection based on otsu)

在计算鬼成像当中，用于生成计算散斑，有了计算散斑 可以做仿真或者其他用途(In the calculation of ghost imaging were used to calculate the generating speckle, speckle can do with computing simulation or other purposes)
