An ORB descriptor Mat object contains X rows (X depending on the max number of features) which represent the features descriptors and 32 columns in which are stored integers between 0 and 255 which represent the descriptor elements. My assumption is that the binary representation of the descriptor is to change these integers to their binary representation (8 bits each, 8*32=256 which is ORB descriptors size) and concatenate them (please correct me if I'm wrong).

Has OpenCV an automatic way to deal with this? converting the int representation to actually binary?
