SpotIt!An Interactive Identikit System

Abstract In this paper we present a system for browsing large mug-shot databases and creating identikits of photographic quality. The two functions are interrelated: the available database provides direct feedback to the user building the identikit and the identikit itself can be used as an access key to the image database. SpotIt! provides a virtually unlimited set of alternative features that can be browsed efficiently in the appropriate context, interactive holistic feature modification coupled to syntactic access to a feature database, and quantitative, automatic computation of face similarities, providing real-time feedback of the system which constantly shows the most promising matches to the identikit being built.
