数字图像处理，边缘提取，分割，湖面面积计算matlab程序(Image processing, edge detection, segmentation, the lake area)

指导滤波，类似于双边滤波的效果，但是速度很快(guided filter)

HOG adaboost pedestrian-detect

亚像素角点定位函数代码,输入参数为角点像素级粗略坐标,输出精确的亚像素级角点坐标(corner subpixel positioning function code, the input parameters for the corner pixel rough coordinates, Output precision Subpixel corner coordinates)

三边滤波器，能够实现平滑滤波的同时进行边缘保持。同时对脉冲噪声有优良的滤波效果。(trialateral filter)

经典的斑块分析算法，计算Blob的源码，算法很好。(Classical plaque analysis algorithms to calculate Blob source code, algorithms very well.)

评价描述子的好坏，能给出重叠率、正确率和查错率等(Evaluation of descriptors)

说明：  该代码的主要功能是图像边缘检测，利用霍夫变换确定圆的位置，并进行缺陷定位着色等操作(The main function of the code is image edge detection, using HOF transform to determine the location of the circle, and the location of defects such as coloring operations)

为数字图像水印提供多种攻击方式，其中包括JPEG压缩、高斯低通滤波等多达十种攻击方式。(Offers a variety of attacks of digital watermarking ,including the jpeg compression, Gaussian low-pass filtering, up to ten different attacks)

说明：  进一步讨论怎么样进行虹膜眼睛的位置确认，区域生长法确定内圆轮廓(To further discuss how to confirm the position of the iris eye and determine the inner circle contour by region growth method)
