| 摘 要： | 介绍一种基于非下采样轮廓波Nonsubsampled Contourlet(NSCT)和矩阵F-范数的图像检索(CBIR)技术。首先对图像进行NSCT变换,然后将变换结果用矩阵F-范数构建特征向量,设计了两个特征向量相似度度量,最后给出加权相似度实现了图像检索。实验结果表明,该技术具有很好的检索率。

| Abstract: | A new method for texture image retrieval based on Nonsubsampled Contourlet(NSCT) and matrix F-norm is proposed.Firstly,image decomposition is conducted with non-subsampled Contourlet transform.Then the F-norm of each sub-image and each sub-image’s texture features is computed,similarity of the two feature vector is designed.Finally,the image retrieval is achieved based on weight distance measure.The performance of proposed image retrieval method is better than that of the approach of the traditional method. |
