a new ROI based color image retrieval using DWT is proposed.Firstly
the ROI are extracted in DWT domain by using the human visual characteristic and K-mean clustering.Secondly
the local energy of wavelet coefficients of ROI is used for the texture feature
the mean values and standard deviations are used for the color feature
and the weight center coordinate of ROI is used for the location feature.Finally
the similarity between images is computed according to the ROI' above features.Experimental results show that our image retrieval is more accurate in retrieving the user-interested images when there are ROI in the image(especially for the image with simple background).
