Title: Texture Image Retrieval Based on Contourlet Transform
Abstract: A texture image retrieval algorithm based on Contourlet transform was proposed.Firstly,texture images were transformed based on Contourlet domain,then the rotation invariance was improved by adjusting sequence of sub-band energy parameters.Then means and standard deviation of coefficients matrix in different scale and various directions were extracted to form feature vectors.Finally,similarity measurement was implemented by using Canberra distance.Experimental results show that the new method has better retrieval performance and the properties of rotation invariance.
