In this paper an algorithm for fast querying in images database is presented. It uses multiresolution technique, all the images are decomposed in few levels and the most important wavelet detail coefficients are selected to compose images pseudo-hashes. When searching for an image-query in the database, the pseudo-hashes of the images are considered instead of the images themselves.
