对图像添加各种噪声 高斯噪声 淑盐噪声(Add a variety of image noise, Gaussian noise, noise, salt-sook)

个人感觉最好用最小二乘支持向量机工具箱，特与大家共享！(Personal feeling is best to use least squares support vector machine toolbox, special to share with everyone!)

基于VisualC_和DCMTK的医学DICOM图像显示与调窗,同时在MFC 下完成鼠标拖动进行窗宽/窗位的调节(Medical image of DICOM VisualC_ and DCMTK display and window based on, at the same time in MFC complete the mouse to drag the window width/window regulator )

混合输入输出相位恢复算法的小程序，入门学习(HIO phase recovery algorithm small program, learning portal)

matlab编写的CT图像的滤波反投影程序(matlab prepared CT images of the filtered back-projection program)

改进的harris角点检测代码，应用于基于特征的遥感影像配准中，在经典harris算子基础的改进，提高角点检测的准确度(improvement of harris corner detection program，applied in RS imagery registration based on features，the operator improved on the base of the classical one，the accruacy has been enhanced )

1.设计一个程序，对一幅灰度图像的实现如下几何变换,1)放大为原图1.5倍 2)绕中心旋转30度(CW) 3)采用偏移量插值实现一个透视变换. 灰度差值用最近邻插值和双线性插值 2. 绘制一幅灰度图像的梯度幅度图像（三点法求梯度），针对梯度幅度图像合理的选择一个阈值（通过试验即可）将其二值化，以获得图像边缘检测图像。 ((1) design a program, a grayscale image as geometric transformation, zoom 1) for 1.5 times the original 2) around the center of rotation of 30 degrees (CW) 3) interpolation of the offset to achieve a perspective transformation.gray level difference between the nearest neighbor interpolation and bilinear interpolation (2) draw a grayscale image of the gradient magnitude image (three-point method seeking gradient), the gradient magnitude image is reasonable to select a threshold value (the test can be) the second value to the image edge detection image.)

本程序实现了提取图像中直线的功能。能够很好地提取出位于边缘上的直线段，其结果表示为两端端点坐标以及线段宽度(This program realizes the function of extracting the edge line in the image.The straight line segment at the edge can be extracted well, and the result is expressed as the end point coordinates and line segment width at both ends.)
