Contourlet

用于求取灰度图光斑的中心，可以用于寻找光斑图像的中心，如激光光斑，(Used to strike a grayscale facula center spot can be used to find the center of the image, such as the laser spot,)

说明：  基于四元数的matlab处理工具包，利用四元数实现了很多图像处理的功能，并提供了api供大家使用(Quaternion-based processing tool kit of matlab, the use of quaternions to achieve a lot of image processing functions, and to provide for your use of the api)

根据Dalal提出的HOG特征算法编写，代码简单，注释清楚，根据所处理图像的名称路径修改后可生成36*105的特征向量。(The algorithm proposed by Dalal HOG feature writing code simple, clear annotation feature vector can generate 36* 105, modified according to the name of the image processing path.)

实现两幅图像匹配。应用SSD+SAD+NCC算法的匹配，很好用的程序(Realizing Two Image Matching.Application of SSD+SAD+NCC algorithm matching, very useful program)

BBO I类匹配角计算 通过修改相应的参数可以计算其他负单轴晶体的I类匹配角(BBO Class I match angle calculated by modifying the parameters can be calculated other negative uniaxial crystals Class I match angle)

指纹识别demo 演示方向图、roc曲线(fingerprint demo show orientation and ROC curve)

1.本程序功能包含显示直方图，OTSU的单值分割，OTSU的二值分割,OTSU的三值分割 2.在OTSU的分割时，通常情况下我们是通过类间方差得到一个分割阈值，但是有时候我们需要得到各灰度级别的目标，那么采取多值分割是 很必要的，通过改进得到OTSU的多值分割方法 3.本程序另外还有显示直方图，计算程序运行时间，处理结果以新的窗口显示等细节，这部分适合MFC初学者。(1. This procedure shows the histogram feature, OTSU single segmentation, OTSU binary segmentation, OTSU three segmentation 2. OTSU segmentation, it is usually the case we are through the between-cluster variance by a partition threshold , but sometimes we need to be the gray level of the target, then the multi-segmentation is necessary, through improved access to multi-OTSU segmentation methods 3. This procedure in addition to show the histogram to calculate run time, treatment the results of a new window display the details of this part of MFC for beginners.)

用代数迭代算法ART重建图像，含MATLAB代码(image reconstruction using ART algorithms (MATLAB code))

图像恢复：快速非局部均值滤波--A.Buwades等人提出的非局部均值滤波的快速实现方法(Image restoration: the proposed fast non-local means filtering- A. Buwades non-local means filtering Fast Implementation)

guided_filter滤波器。对于图像处理方面有用。(filter. It is useful for image processing.)
