【从零学习OpenCV 4】分割图像——Mean-Shift分割算法 - 知乎
The intuition behind the meanshift is simple. Consider you have a set of points. (It can be a pixel distribution like histogram backprojection). You are given a small window (may be a circle) and you have to move that window to the area of maximum pixel density (or maximum number of points). It is illustrated in the … Ver mais In this chapter, 1. We will learn about the Meanshift and Camshift algorithms to track objects in videos. Ver mais Did you closely watch the last result? There is a problem. Our window always has the same size whether the car is very far or very close to the camera. That is not good. We need to … Ver mais OpenCV comes with a Python samplefor an interactive demo of camshift. Use it, hack it, understand it.
