使用opencv循环遍历像素 [英] Cycle through pixels with opencv

问题描述

如何使用opencv循环使用图像，就像它是一个2d数组，以获取每个像素的rgb值？

How would I be able to cycle through an image using opencv as if it were a 2d array to get the rgb values of each pixel? Also, would a mat be preferable over an iplimage for this operation?

推荐答案

如果你使用C ++，使用opencv的C ++接口然后您可以通过 http ：//docs.opencv.org/2.4/doc/tutorials/core/how_to_scan_images/how_to_scan_images.html#the-efficient-way 或使用cv :: Mat :: at（），例如。

If you use C++, use the C++ interface of opencv and then you can access the members via http://docs.opencv.org/2.4/doc/tutorials/core/how_to_scan_images/how_to_scan_images.html#the-efficient-way or using cv::Mat::at(), for example.
