2017-07-19 02:00:15 -0600	commented answer	Unsupported format or combination of formats in buildIndex using FLANN algorithm For situations where the dataset is large and the speed matters a lot, using FLANN was the only option. This conversion was the need of the hour. Can't use SURF(need to pay for that), so the only option seems to be using ORB with FLANN. Any other suggestions in my case of usage??
2017-07-19 01:30:02 -0600	commented answer	FLANN error in OpenCV 3 I had the same problem it seems that Flann needs the descriptors to be of type CV_32F. Try doing this before matching descriptors_1.convertTo(descriptors_1, CV_32F); descriptors_2.convertTo(descriptors_2, CV_32F);
