Real-time facial recognition and verification system
First Claim
1. A system for refining an object within an image based on color, the system comprisinga storage element for storing flesh tone colors of a plurality of people, defining means for defining an unrefined region of interest corresponding to at least part of the object in the image, the unrefined region of interest including flesh tone colors, and combination means for combining the unrefined region of interest with one or more of the flesh tone colors stored in the storage element to refine the region of interest to ensure that at least a portion of the image corresponding to the unrefined region of interest having flesh tone color is incorporated into the refined region of interest.

Abstract
A system and method for acquiring, processing, and comparing an image with a stored image to determine if a match exists. In particular, the system refines the image data associated with an object based on pre-stored color values, such as flesh tone color. The system includes a storage element for storing flesh tone colors of a plurality of people, and a defining stage for localizing a region of interest in the image. A combination stage combines the unrefined region of interest with one or more pre-stored flesh tone colors to refine the region of interest based on color. This flesh tone color matching ensures that at least a portion of the image corresponding to the unrefined region of interest having flesh tone color is incorporated into the refined region of interest. Hence, the system can localize the head, based on the flesh tone color of the skin of the face in a rapid manner. According to one practice, the refined region of interest is smaller than or about equal to the unrefined region of interest.

22. A method of refining an object within an image based on color, the method comprising the steps of
storing flesh tone colors of a plurality of people in a storage element, defining an unrefined region of interest corresponding to at least part of the object in the image, the unrefined region of interest including flesh tone colors, and combining the unrefined region of interest with the flesh tone colors stored in the storage element to refine the region of interest to ensure that at least a portion of the image corresponding to the unrefined region of interest having flesh tone color is incorporated into the refined region of interest, the refined region of interest being smaller than or about equal to the unrefined region of interest.

36. A facial recognition and identification system for identifying an object in an image, comprising
an image acquisition element for acquiring the image, defining means for defining an unrefined region of interest corresponding to at least part of the object in the image, the unrefined region of interest including flesh tone colors, combination means for combining the unrefined region of interest with the flesh tone colors to refine the region of interest to ensure at least a portion of the image corresponding to the unrefined region of interest that includes flesh tone color are incorporated into the refined region of interest, the refined region of interest being smaller than or about equal to the unrefined region of interest, said refined region of interest corresponding at least in part to the object, and a recognition module for determining whether the acquired object matches a pre-stored object, whereby said system recognizes the object when the object matches the pre-stored object.
