OPENCV做图像变形的经典代码啊，适合比较初级的同学看看(OPENCV do image warping the classic code ah, suitable for elementary students to see more)

检测图片中的角点，将图片读入后转换为灰度图以便处理。 2.通过用Dx=[-1,0,1;-2,0,2;-1,0,1]和灰度图片的矩阵卷积得到灰度图片在x方向上的导数矩阵Ix，矩阵中（i，j）处的元素代表灰度图片矩阵（i，j）处在x方向的导数Ix(Detection of corners in a picture)

sift算法图像特征提取，用于图像定位及目标跟踪(Using SIFT algorithm to extract image feature)

基于matlab的钢筋计数方法，有ui界面(MATLAB-based steel bar counting method with UI interface)

说明：  内含M文件 利用对数比实现，两幅多时空SAR图像变化差异图 (Logarithm figure than the implementation differences )

能将一幅灰度图像根据用户自己给定的彩色图像将其对应的转化为真彩色图像。(Gray image can be processed into rgb image.)

计算局部形状描述符梯度方向直方图（HOG），直接输入图像即可用。(Calculate the local shape descriptors gradient orientation histogram (HOG), the input image can be used directly.)

moravec算子提取特征点，然后用相关度进行匹配(moravec operator feature point extraction, and then match the correlation)

此代码实现了基于Multiphase的level set图像分割算法，得带速度快，通过调整参数可以获得很好的分割效果。(This code-based Multiphase the level set image segmentation algorithm, was with the speed, by adjusting the parameters can get very good segmentation results.)

一个医学图像配准的源程序，希望对大家有用(A medical image registration of the source, in the hope that useful to everybody)
