Webface. We compress this set into a histogram. A database of histograms, one per object, is sampled in a training phase. During recognition, sensed surface data, as may be ac-quired by stereo vision, a laser range-scanner, etc., are pro-cessed and compared to the stored histograms. We evaluate the match quality by six different criteria that are ... WebC++ implementation of the SHOT 3D descriptor. SHOT is an implementation of the algorithms described in: F. Tombari, S.
