US 12,651,479 B2 · Fast face image capture system

Abstract

A fast face capture system and process for identifying an individual as the individual walks through an area. A set of raw images is streamed from at least one camera for detecting individuals entering the area. The images are searched for a face. If a face is detected, a tracking ID is assigned; and a timer and face tracking is commenced to obtain a sequence of candidate images for each individual as the individual walks through the area. A maximum quality image is selected from the candidate images for each individual based on at least one quality metric, the elapsed time, and the quality select count of the candidate images. The maximum quality image is submitted for matching with a verified image of the person. The invention has particular application to security check points for quickly matching the face of the moving person with a previously acquired and verified identity.

Dependent claims

A face recognition system for identifying a person as the person is moving through a designated area, the system comprising:

a camera aimed at the designated area;
at least one processor operable to perform:
face tracking of the person as the person moves through the designated area based on receiving a plurality of consecutive images from the camera;
and
selecting at least one candidate image for matching from the plurality of consecutive images based on an image quality metric, a time elapsed, and an image quality count, wherein the selecting comprises:
evaluating whether an image from the plurality of consecutive images meets a minimum image quality based on the image quality metric;
incrementing the image quality count when the image meets the minimum image quality;
and
repeating the evaluating and incrementing steps for each of at least a plurality of the plurality of consecutive images until the image quality count reaches a threshold count value;
and
a display, wherein the at least one processor and the display are operable to show on the display live images of the face of the person during face tracking.
