Abstract:
A better content based image retrieval is possible when the image pseudo hash is able to work in the wavelet transform. While decomposing the images, we identified the important wavelet detail  coefficients to compose the pseudo-hash. We considered the pseudo-hashes of the images rather than  the images directly to search the digital images in the large databases.
