Person tagging in an image processing system utilizing a statistical model based on both apperance and geometric features
First Claim
1. A method of person tagging in an image processing system, the method comprising the steps of:
- processing a sequence of images to generate a statistical model for each person to be tagged, the statistical model incorporating at least one appearance feature and at least one geometric feature of the tagged person;
applying the model to at least one subsequent image in order to perform at least one of a detection operation, a location operation and a tracking operation for the tagged person; and
controlling an action of the image processing system based on a result of the at least one operation.

Abstract
An image processing system processes a sequence of images 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 is controlled based on a result of the operation.

20. An apparatus for use in providing person tagging in an image processing system, the apparatus comprising:
a processor operative to process a sequence of images to generate a statistical model for each person to be tagged, the statistical model incorporating at least one appearance feature and at least one geometric feature of the tagged person, the processor being further operative to apply the model to at least one subsequent image in order to perform at least one of a detection operation, a location operation and a tracking operation for the tagged person, and further wherein an action of the image processing system is controlled based on a result of the at least one operation.

21. An article of manufacture comprising a storage medium for storing one or more programs for use in providing person tagging in an image processing system, wherein the one or more programs when executed by a processor implement the steps of:
-
processing a sequence of images to generate a statistical model for each person to be tagged, the statistical model incorporating at least one appearance feature and at least one geometric feature of the tagged person; and
applying the model to at least one subsequent image in order to perform at least one of a detection operation, a location operation and a tracking operation for the tagged person;
wherein an action of the image processing system is controlled based on a result of the at least one operation.
