Claim One:
1. A method of finding a most likely match for a target facial image in a data base of facial images comprising; creating a data base of facial images in digitized form stored in a digital storage apparatus, digitizing a target facial image from a video image into a digital memory apparatus, establishing a value system to provide a value within the system which is a function of quantization of facial feature measurements, selecting a set of facial features to be subjected to quantization on the digitized target facial image and on the digitized data base facial images, locating the set of facial features on the target image and on each of the data base images by placing a window in a determined position for a selected first facial feature and within said window locating a point or points defining the first facial feature location and locating other facial features directly or indirectly by determined relationship to said point or points defining said first facial feature. quantizing the set of facial features of each facial image in the data base, finding the value in the value system which responds to the quantization of each facial image in the data base, quantizing the target facial image, finding the value in the value system which responds to the quantization of the target image, comparing the value in the value system which responds to the quantization of the target facial image, to each value in the value system which responds to the quantization of each of the facial images in the data base, ordering the facial images in the data base according to closeness of the value in the value system for the data base facial image to that of the target facial image.
