基于轮廓的形状射线描述模型
Ray shape model based on contour
摘要
Abstract
A novel contour-based shape descriptor and shape matching method is proposed. Contour is extracted and points are evenly sampled on the contour. Distances between reference point and sample points, directions of contour on sam-pling points and the spatial relations between sampling points are used to represent the shape characteristics. Then scale, rotation and translation invariance on shape matching are obtained through maximum voting on different scales, orienta-tions and positions. A similarity scoring scheme that integrates local and global features is proposed to perform object matching and detection. The experimental results show that ray shape model can be used in shape matching for objects with clear contours and detecting objects in complex images.关键词
