一种基于半径和角度直方图描述形状的图像检索方法
An Image Retrieval Method Based on Radius and Angle Histograms Shape Descriptor
摘要
Abstract
In order to satisfy that the shape descriptors must be of translation, scale, rotation transformation invariance, this paper uses a shape descriptor based on region; radius histogram descriptor, and adopts a normalization processing of the radius size computation to solve the problem of scale invariance; computes the angle histogram descriptor to obtain the radial shape characteristics, and computes the module information vector of its Fourier Transform to solve the problem of rotation invariance. The joint of radius and angle histogram descriptors makes the retrieved shapes be identified by people's eyes very perceptually. Experimental results show that this method is simple and efficient.关键词
