Semantics in visual information retrieval
Carlo Colombo, Alberto Del Bimbo, Pietro Pala · IEEE Multimedia · 1999
A compositional approach increases the level of representation that can be automatically extracted and used in a visual information retrieval system. Visual information at the perceptual level is aggregated according to a set of rules. These rules reflect the specific context and transform perceptual words into phrases capturing pictorial content at a higher, and closer to the human, semantic level.
