在JavaCV中传递给cvFindContours（）的参数是什么？ [英] What are the parameters passed to cvFindContours() in JavaCV?

问题描述

请解释一下 cvFindContours 方法，它需要什么参数？

Please can some one explain about cvFindContours method and what are the parameters that it required?

例如，以下是使用OpenCV的代码：

For example, here's code using OpenCV:

hierarchy = cv2.findContours(thresh, cv2.RETR_LIST, cv2.CHAIN_APPROX_SIMPLE)

请说明一下这使用JavaCV？

Please can some one explain how to write this using JavaCV?

推荐答案

正如Mohammad所提到的意见，这三个参数是 header_size ， >和方法。您可以使用此方法如下

As comments mentioned by Mohammad those three parameters are header_size, mode and method. You can use this method as follows

    IplImage src = cvLoadImage(path);//hear path is actual path to image
    IplImage grayImage    = IplImage.create(src.width(), src.height(), IPL_DEPTH_8U, 1);
    cvCvtColor(src, grayImage, CV_RGB2GRAY);
    cvThreshold(grayImage, grayImage, 127, 255, CV_THRESH_BINARY);
    CvSeq cvSeq=new CvSeq();
    CvMemStorage memory=CvMemStorage.create();
    cvFindContours(grayImage, memory, cvSeq, Loader.sizeof(CvContour.class), CV_RETR_LIST, CV_CHAIN_APPROX_SIMPLE);

希望这可能有助于您了解此方法。

Hope this might help you to understand this method.
