Abstract

Discrete wavelet transform is used to create pseudo-hashes based on content of images and they are stored in a database. The images are decomposed in few levels and the most important wavelet coefficients are selected. The pseudo-hash contains statistical parameters of the coordinates of the coefficients. When searching a large database for images that match a query-image, the similarity of images pseudo-hashes is considered instead of the images themselves.
