HTS and HTSn: New shape descriptors based on Hough transform statistics ?
We show that the Hough space is a good source of information for shape analysis. We developed new shape descriptors based on the Hough transform, HTS and HTSn. HTS and HTSn are more accurate than important shape descriptors of the literature. HTS and HTSn have linear complexity, being faster than other descriptors, e.g. BAS.
