Improved Efficiancy of CBIR using Contourlet Transform

Content-based image retrieval (CBIR) is an impotent research area for manipulating large amount of image database and archives. In this paper we explain the efficiency retrieval rate of content based image retrieval system using contourlet transform. the multiresolution using the Laplacian pyramid (LP).And the directionality can be analyzed by using the Directional Filter bank(DFB) .In CBIR system using Contourlet Transform based features directionality and anisotropy are made it powerful. Improved results in terms of retrieval efficiency and less complexity are observed in recent work .The distance measures VIZ., Manhattan distance and minkowaski distance are used in similarity measures in the proposed CBIR system
