Abstract: Disclosed is a system and method for image processing and image subject matching. A circuit and system may be used for matching/correlating an object/subject or person present (i.e. visible within) within two or more images. An object or person present within a first image or a first series of images (e.g. a video sequence) may be characterized and the characterization information (i.e. one or a set of parameters) relating to the person or object may be stored in a database, random access memory or cache for subsequent comparison to characterization information derived from other images.
