Image similarity models and the perception of artistic representations of natural images

Next generation content-based retrieval systems for image and multimedia databases will benefit from utilizing higher level models of human visual processing. This includes incorporating models of early vision as well as more specialized areas like the IT cortex, which is thought to be important in object recognition. Artistic representation is typically based on abstraction of visual content in images. Analogies of various modes of artistic representation can be see in scientific investigations of the visual system. These two observations suggest that an examination of traditional artistic representation may aid in constructing robust feature spaces for content abstraction in image retrieval. In addition, artistic renderings can be used to test the performance of models of image similarity in existing content-retrieval systems.
