基于非下采样Contourlet信息熵的纹理图像检索
Texture Image Retrieval Based on Nonsubsampled Contourlet and Information Entropy
摘要
Abstract
A new method for texture image retrieval based on nonsubsampled Contourlet and information entropy was proposed. Firstly, image decomposition was conducted with nonsubsampled Contourlet transform. Then the energy of each sub-image was computed, and the sub-image was merged through its energy in order to get the histogram. Finally the information entropy was computed with the histogram. The proposed image retrieval method's performance was better than that of the approach of the traditional method based on the multiresolution theory.关键词
