Gaussian shape context descriptors
摘要
Abstract
The shape context ( SC) descriptors based on the Gaussian window ( GSC) are proposed . The GSC descriptors can be used to match shapes . Encircling the reference point , the GSC sets up a group of Gaussian window functions . According to the Euclidean distance between the center points and the sampling points , the GSC describes the spatial relations between sampling points based on the shape descriptors calculated by Gaussian window functions by the use of as many sampling points as possible . More accurate correspondences between two shapes are determined by comparing the similarities of the shape descriptors . Experimental results show that the GSC can find more accurate correspondence relations and provide a good initial value . The proposed descriptors can also make the matching algorithm converge fast , while keeping a good anti‐noise and robust performance compared with SC .关键词
