Abstract: A method (and system) for specifying the region layout of objects in an affine invariant manner as a set of affine intervals between pairs of regions, includes representing database and query regions using affine intervals along with their region identity, matching query region layout to layout of database image regions using an index structure, and retrieving relevant images of the database by hashing for dominant hit regions in the index structure.
