此程序为优化后的分水岭算法,避免了图像过分割 I= imread('D:\Images\pic_loc\1870405130305041503.jpg'); imshow(I); h=fspecial('sobel'); %h = fspecial(type) creates a two-dimensional filter h of the specified type. fspecial returns h as %a correlation kernel, which is the app
在官方示例中,Motion-Based Multiple Object Tracking和Using Kalman Filter for Object Tracking都使用了下面两个算法进行物体的识别 1.vision.ForegroundDetector 原理:The ForegroundDetector System object compares a color or grayscale video frame to a background model to determine whe
