Patent ID: 8204281

Claim:
A method to correct artifacts in a biometric image assembled from a plurality of partial biometric images, comprising: acquiring a first partial biometric image as a reference image; performing a comparison between the reference image and a second subsequent partial biometric image using a comparison function; determining if the result of using the comparison function to compare the reference image and the second subsequent partial biometric image is less than a preset limit; if the result is less than the preset limit, discarding the second subsequent partial biometric image; if the result is not less than the preset limit, setting the second subsequent partial biometric image as the reference image; repeating the performing, determining, discarding, and setting steps until the comparison is performed for each of the plurality of partial biometric images; reassigning one of a time stamp and a position indicator for remaining subsequent partial biometric images subsequent to any discarded partial biometric image or images by using the difference in the time stamp or position indicator between a partial biometric image just prior to a first discarded partial biometric image in the any discarded partial biometric image or images and a partial biometric image subsequent to a last discarded partial biometric image in the any discarded partial biometric image or images, and utilizing one of the reassigned time stamp and position indicator for each remaining subsequent partial biometric image, unless and until a further reassigning step occurs, to assemble the plurality of partial biometric images into a redacted biometric image.
