Contourlet Texture image retrieval system using the features combined by energy and standard deviation of subband coefficients has better performance than the same structure system based on wavelet transform due to contourlet has better directional information representation than wavelet transform. In order to improve the retrieval rate further, a new texture image retrieval system was proposed in...
Texture image retrieval system using contourlet transform has better performance than the same structure system based on wavelet transform due to contourlet's better directional information representation than wavelet transform. In order to improve the retrieval rate further, a dual-tree complex contourlet transform based texture image retrieval system was proposed in this paper. In the system, the...
To improve the retrieval rate of contourlet transform texture image retrieval systems and reduce the redundancy of contourlet which cost two much time in building feature vector database, a wavelet-contourlet transform retrieval system was proposed. In the system, wavelet-contourlet was constructed by wavelet transform at coarser scales and contourlet transform at finer scales, the mixed transform...
To improve the retrieval rate of contourlet transform retrieval system,a new contourlet retrieval system was proposed.The feature vectors were constructed by cascading the absolute mean energy and kurtosis of each sub-band contourlet coefficients and the similarity measure used here is Canberra distance. Experimental results on 109 brodatz texture images show that using the features cascaded by absolute...
