Hi all, i wanna store a descriptor which is computed by akaze->compute(grey, kpts, desc); into some DB. For that purpose I would need the binary descriptor in some other format than cv::Mat desc;. I would prefer some enum or bool container like std::vector<bool>. How can I get the values out of desc??

careful ! if you're using DESCRIPTOR_KAZE, you'll get CV_64F features.

also, even if you're using CV_8U fatures, a vector<bool> is the wrong container to store them (there's no guarantee, that it will use uchar elements)
