基于小波的去噪算法，采用BAYES原理选取阈值，源代码，参考文献：Adaptive Wavelet Thresholding for Image Denoising and Compression(Wavelet-based denoising algorithm using the principle to select threshold BAYES, source code references: Adaptive Wavelet Thresholding for Image Denoisingand Compression)

通过执行程序，可以实现对物体视差图的生成，进而可以实现深度图。(Through the implementation of the program, you can achieve the object disparity map, and then you can achieve depth map.)

用surf和ransac实现两幅图像配准(Registration of two images with surf and RANSAC)

SIFT 尺度不变特征提取算法 可参考可运行有测试图片(SIFT with test picture and it can work well)

[SIAM]Nonlocal Active Contours该文件包含论文及代码，主要内容是在水平集图像分割中引入non-local的性质，构造能量泛函，进行图像分割(this file include both paper and code, the main idea is utilize the non-local peperty in level set method for image segmentation )

1.模式匹配：子串在主串中的定位，也叫字符串匹配。模式匹配成功是指在主串S中能够找到模式串T，否则，称模式串T在主串S中不存在。 2.模式匹配的应用在非常广泛。例如，在文本编辑程序中，我们经常要查找某一特定单词在文本中出现的位置。 3.模式匹配算法的研究能极大地提高文本编辑程序的响应性能。 (1 pattern matching: substring positioned in the main string, also called string matching. Pattern matching refers success can be found in the main string S pattern string T, otherwise known as pattern string T does not exist in the main string S. 2 pattern matching in a very wide range. For example, in a text-editing program, we often have to find the location of a particular word appears in the text. 3 study of pattern matching algorithms can greatly improve the response performance of text editing program.)

基于离散余弦变换的数字水印，包括水印的嵌入和提取以及常间的各种水印攻击(Discrete cosine transform based on digital watermarking, including the watermark embedding and extraction, as well as between the various watermark attacks often)

背景差分法运动目标检测，建立背景模型，然后使用当前模型与背景模型相减，再和阈值相比较，比阈值大的即判断为有运动目标，比阈值小的即判断为没有运动目标，阈值大小可以自己适当调试，根据经验值设置最佳阈值。(Background difference method is used for moving target detection and setting up background model, then using current model and background model subtracting, and comparing with threshold, it is judged to have moving target compared with the threshold value, which is smaller than threshold. The size of threshold can be adjusted properly, and the best threshold is set according to experience value.)

图像金字塔分解与图像金字塔重构matlab 程序，我试过了，很不错(Image pyramid decomposition and reconstruction of image pyramid matlab program, I tried, very good)

CT重建图像时，先用BM3D滤波，然后运用经典的非局部平均去噪，效果很好。。(CT reconstruction image, the first with BM3D filter, and then use the classical non-local average denoising, very good. .)
