Signature of histograms of orientations
WebJun 28, 2024 · The peaks of the smoothed histogram marked by the red line are given by the green circles. The highest peak determines the primary orientation and the threshold for secondary orientations given by the dotted black line. For this sample shape, the primary orientation is at, and the secondary orientations are at and 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 ...
