2013-08-28 15:36:32 -0600	commented question	error: (-215) func != 0 in function convertTo It returns an std::vector<KeyPoint>. I am trying to get a CV_32F mat that contains this list of points. Thanks
2013-08-28 15:33:10 -0600	commented answer	error: (-215) func != 0 in function convertTo Thank you very much for this detailed response! I am trying to build a kd-tree with cv::flann::Index. So, I was trying to build it with a set of keypoints that I have by inserting them to a Mat but in order to build it I need a CV_32F mat and I can't get it right. How do you think I can solve this problem ? Thanks
2013-08-28 10:45:49 -0600	asked a question	error: (-215) func != 0 in function convertTo Hi, In the following code I get an opencv assertion and I don't understand why. Any help will be very much appreciated. The code: `Mat m(pm->get_current_tracked_keypoints()); // after this line: m.type=7 and m.depth=7 Mat m1; m.convertTo(m1, CV_32F);` The error: `OpenCV Error: Assertion failed (func != 0) in convertTo, file /build/buildd/opencv-2.3.1/modules/core/src/convert.cpp, line 937 terminate called after throwing an instance of 'cv::Exception' what(): /build/buildd/opencv-2.3.1/modules/core/src/convert.cpp:937: error: (-215) func != 0 in function convertTo` Thanks
