Second generation contourlet transform based texture image retrieval system

A second generation contourlet transform based texture image retrieval system is proposed.In the system,sub-bands en- ergy and standard deviations in second generation contourlet domain are cascaded to form feature vectors,and the similarity metric is Canberra distance.Experimental results on 109 texture images from Brodatz album show that second generation contourlet transform based image retrieval system under the same system structure is superior to that of the original contourlet transform with almost same length of feature vectors,retrieval time and memory needed.
