As far as I can tell this has not been implemented yet, has anyone successfully implemented this:
DescriptorExtractor* extractor; //Any extractor gpu::BruteForceMatcher_GPU_base matcher; //L1, L2, HAMMING, etc BOWImgDescriptorExtractor* bowide = new BOWImgDescriptorExtractor(extractor, matcher);
Any help or feedback would be much appreciated!
