Abstract

Keypics are graphical metadata intended for indexing of images on the Internet. They are conceived as hand-drawn sketches, not restricted to a definite set. An obvious difficulty when dealing with keypics is that they elude rigid geometric treatment. A proposal of solution comes from Size Functions. This paper is the report of a complete experiment on 494 keypics with Size Functions based on three measuring functions (distances, projections and jumps) and their combination.
