PERSON TAGGING IN AN IMAGE PROCESSING SYSTEM UTILIZING A STATISTICAL MODEL BASED ON BOTH APPEARANCE AND GEOMETRIC FEATURES

摘要

An image processing system (10) processes a sequence of images (25) to generate a statistical model for each of a number of different persons to be tagged so as to be identifiable in subsequent images. The statistical model for a given tagged person incorporates at least one appearance feature, such as color, texture, etc., and at least one geometric feature, such as shape or position of a designated region of similar appearance within one or more images. The models are applied to subsequent images in order to perform a person detection, person location and/or person tracking operation. An action of the image processing system (10) is controlled based on a result of the operation.
