i have to use some of cv methods that take cvMat and to use ofxCvImage i have to do a little workaround:
// pseudocode IplImage * origin = ofxCvImage::getCvImage() CvMat stub, *dst_mat; dst_mat = cvGetMat(src_img, &stub, 0, 0); cv_foo_method_that_uses_cvMat(..) // and then return back from cvMat to IplImage to ofxCvImage
what is the best way? then, basing on this topic: http://stackoverflow.com/a/5192612/433685
Based on the ‘c++’ tag you have in your question: You should not use it, you should use cv::Mat. Every IplImage is a cv::Mat internally.
IplImage is only used in the C API. It is a kind of CvMat and holds image data. Its name origins from OpenCV roots (Intel IPL).
It is not relevant anymore if you use C++ API of OpenCV.
i thought: why ofxCvImage is based on IplImage and not on cvMat? how can i add some methods that make this kind of “cast” easy?
EDIT: conversion between IplImage and cvMat are grabbed from here: http://wangpengnorman.blogspot.com/2009/06/transform-between-cvmat-and-iplimage.html
