自己编写的图像腐蚀与膨胀matlab代码，经试验证明与matlab中自带的腐蚀和膨胀函数运行效果相同，可供初学图像处理的同学参考使用。(The image corrosion and expansion matlab code written by myself has been proved to be the same as the corrosion and expansion function of the matlab. It can be used by students who are ready for beginner image processing.)

实现图像边缘的傅里叶描述子，可用于边缘检测，形状分析。(Matlab achieve image edge of the Fourier descriptors, can be used for edge detection, shape analysis.)

Apprehend Screen Capture Component Version 4.2 A non-visible component to capture images. Freeware with source. Includes Four Demos with source and EXE s. 3,550 KB. 10/09/2005

完成图片的哈哈镜效果，如三角形，圆形，波浪形，弯曲等等(change the picture to any shape you want)

说明：  聚类分析作业，可以对图像根据颜色进行聚类分析，通道数可以自我选择，方便使用。(Clustering analysis can cluster images according to color, and the number of channels can be self-selected for easy use.)

说明：  “求RGB转HSI空间小程序.m”为主函数调用rgb2hsi.m，由于matlab没有自带这个函数，所以自编了一个，用于进行阴影去除。( Seeking RGB to HSI space program. M the main function call rgb2hsi.m, as a result of matlab does not own this function, so a self-compiled, used for shadow removal.)

说明：  傅里叶变换中的角谱衍射理论，GS算法实现(Angle spectrum diffraction theory in Fourier transform, Realization with GS algorithm)

完成对视频帧的四叉树分割，在纹理复杂处分割块较小，在纹理平坦处分割较大(Complete quadtree segmentation of video frames, complex area in texture segmentation smaller, flat larger regional segmentation block in texture)

matlab程序，图像应用处理，可实现散焦模糊篡改图像的定位和分离，实现模糊图像真实性的检测(matlab program, image processing applications can be realized defocus blurred image tampering localization and separation, to achieve authenticity blurred image detection)
