Color Image Retrieval Using M-Band Wavelet Transform Based Color-Texture Feature

Feature extraction algorithm is a very important component of any retrieval scheme. We propose M-band Wavelet Transform based feature extraction algorithm in this paper. The MtimesM sub-bands are used as primitive features, over which energies computed in a neighborhood are taken as the features for each pixel of the image. These features are clustered using FCM to obtain image signature for similarity matching using the Earth Mover´s Distance. The results obtained were compared with MPEG-7 content descriptor based system and found to be superior.
