基于Contourlet变换和不变矩的图像检索方法
The Method of Texture Image Retrieval Based on Contourlet Transform and Moment Invariants
摘要
Abstract
Taking advantage of the characteristics of good sparsity and effective capturing of the smooth contours in natural images of Contourlet transform,we have devised a new method of image retrieval based on Contourlet transform and moment invariants.After decomposing image by Contourlet transform,we have constructed feature vectors by calculating the entropy of high-frequency sub-bands and seven moment invariants of low-frequency sub-bands.The texture similarities of images were computed by the Euclidean's distance with different weights.The experiments show that the method has high precision rate and a good result has been obtained in image classification and retrieval.关键词
