Abstract
This paper addresses the problem of retrieving images from large image databases. The method is based on local grayvalue invariants which ar e computed at automatically detected interest points. A voting algorit hm and semilocal constraints make retrieval possible. Indexing allows for efficient retrieval from a database of more than 1,000 images. Exp erimental results show correct retrieval in the case of partial visibi lity, similarity transformations, extraneous features, and small persp ective deformations.
