Abstract: The present invention relates to a method and apparatus for facilitating identification, particularly where images are of relatively low resolution and also where images may be taken by a moving imaging device, such as a mobile camera. In order to identify persons from images of persons, it is usually necessary to obtain a relatively high-resolution image from which face recognition data can be obtained. The face recognition data can be then matched against a database of many persons face recognition data obtained by an equivalent registration process. Where the images are of relatively low resolution, however, it is difficult to obtain reliable matching. The system and method described here, obtain a number of images of a person to be identified and consolidate data obtained from the images to increase the accuracy of identification. This system can identify persons even where relatively low resolution images and mobile cameras.
