Texture Image Retrieval Based on NSCT and Matrix F-norm
Guan Yonghong · Journal of Sichuan University of Science & Engineering · 2012
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.
