fourier频率中心化

本程序能够综合地实现图像边缘细化，而且程序够复杂。(This procedure can be integrated to achieve the Image Edge thinning, and the procedures complex enough.)

LK光流算法，包括opencv中LK稀疏跟踪的原理，主要是几篇英文文献，另外还有LK的matlab代码(LK optical flow algorithms, including LK sparse tracking opencv in principle, mainly a few in English literature, in addition to LK matlab code)

说明：  一些简单的对图像的处理和直方图均衡化的复刻，可帮助初学者增加认知(Some simple image processing and histogram equalization can help beginners increase cognition)

用matlab编写的多边形画法及填充算法。(yong matlab bian xie de duo bian xing hua fa ji tian chong suan fa . )

风水岭图像分割 Image Segmentation by Watershed(Image Segmentation by Watershed)

此demo演示的是一个能够检测并跟踪道路上的标记线并且在适当时机发出报警的系统，此系统可使汽车在行驶过程中能够避免偏离车道。系统由一台摄像机，一台计算机，以及一个扬声器组成，摄像机采集视频信息交由计算机处理，根据处理结果控制扬声器是否报警。(This demo demonstrates a system that detects and tracks the marking lines on the road and sends out the alarm at the right time, which enables the car to avoid deviating from the driveway during the driving process. The system is composed of a camera, a computer, and a loudspeaker. The video information is processed by the camera to control the alarm of the speaker according to the processing results.)

基于四阶偏微分方程的图像去噪算法，能够有效去除阶梯效应，自己编的程序(image denoising using fourth-order PDEs)
