可以实现Ransac拟合直线和椭圆，很方便，可以直接用。(Can be achieved Ransac fitting a straight line and ellipse, very convenient, and can be directly used.)

说明：  阴影3D重建,对于人脸有效，基于yale2BDB(SFS, effective for face, based on yale 2 B database)

说明：  从单张图片中去除相机抖动造成的模糊的matlab程序，算法见Removing Camera Shake from a Single Image(err)

基于改进的F-S error diffusion算法对彩色图像位数降为8色。其中分配系数采用动态系数(Based on the F-S error diffusion algorithm to improve the color image figures down to 8 colors. The distribution coefficient by using the dynamic coefficient)

计算两个离散变量x和y的联合熵z = H（x，y）。 输入：x，y：两个相同长度的整数向量输出：z：联合熵 可以使用，有利于学习目的(Compute joint entropy z=H(x,y) of two discrete variables x and y. Input: of x, y: two integer vector of the same length Output: z: joint entropy good for learning purposes)

该代码采用opencv环境来实现灰度投影估计电子稳像算法，能够很好地解决视频序列抖动问题。(The code uses the opencv environment to achieve the gray projection algorithm, which can solve the problem of video sequence jitter.)

几种插值方法，双线性，三次，最邻近，sinc(Several interpolation, bilinear, cubic, nearest neighbor, sinc)

数字水印程序，包括多分辨嵌入水印、提取水印程序，盲水印嵌入、提取程序，以及滤波攻击和JPEG攻击程序，PSNR和相似度计算公式（MATLAB）(digital watermarking procedures, including multiresolution embedded watermark, watermark extraction procedure, blind watermark embedding and extraction procedures, Filtering and attack and attack JPEG procedures, PSNR and the similarity calculation formula (MATLAB))

分为行人检测，特征提取，行人跟踪三步，其中最主要的代码也是这个代码的中心是行人跟踪这一部分，我采用的是kalman滤波器进行行人下一帧位置的预测，可以很好的提高行人跟踪的鲁棒性，跟踪结果比较准确。(Into pedestrian detection, feature extraction, pedestrian tracking steps, which is the center of the main code of the code is pedestrian tracking this section, I kalman filter is used to predict the position of the next frame pedestrians, can be a good improvement pedestrian tracking robustness, tracking results more accurate.)

K均值算法实现图像的分割，分割效果可以达到预期的效果(K-means algorithm to achieve image segmentation, segmentation results can be achieved the desired results)
