做什么算法 OpenCV的使用找到的轮廓？

What algorithm does openCV use to find contours?

它是如何工作的？

推荐答案

如果你读了documentation它被提及此函数实现的算法：

If you read the documentation it is mentioned this function implements the algorithm of:

铃木，S和安倍晋三，K.，数字化的拓扑结构分析   通过边界二值图像跟踪。 CVGIP 30 1，第32-46（1985）

Suzuki, S. and Abe, K., Topological Structural Analysis of Digitized Binary Images by Border Following. CVGIP 30 1, pp 32-46 (1985)

OpenCV的是开源的，如果你想看到这是如何实现的只是需要读取code： http://$c$c.opencv.org/projects/opencv/repository/revisions/2.4.3/entry/modules/imgproc/src/contours.cpp

OpenCV is open source if you want to see how this is implemented just need to read the code: http://code.opencv.org/projects/opencv/repository/revisions/2.4.3/entry/modules/imgproc/src/contours.cpp
