System and method for face recognition using three dimensions

A method of facial recognition comprising:

• for each image of a person in a database:
• locating predetermined three-dimensional facial features in the image of the person;
• estimating three-dimensional facial feature location coordinates;
• obtaining the three-dimensional facial feature location coordinates and orientation parameters relative to a coordinate system defined by the location of facial features relative to the predetermined common plane;
• inputting image data representing a plurality of images from the database;
• inputting an image of a subject to be identified;
• locating predetermined three-dimensional facial features in the image of the subject for comparison to the image data from the database;
• estimating three-dimensional facial feature location coordinates of the subject head in the image of the subject;
• obtaining the three-dimensional facial feature location coordinates and orientation parameters in a coordinate system in which the facial features are located in the predetermined common plane;
• comparing the location of the coordinates of the subject to the locations of the coordinates of the images of people in the database;
• and
• determining the identity of the subject.

A system for facial recognition comprising:

• at least one processor;
• at least one input operatively connected to at least one processor and configured to input at least one image of a subject to be identified;
• a database configured to store three-dimensional facial image data comprising facial feature coordinates in a predetermined common plane;
• the at least one processor configured to locate predetermined three-dimensional facial features in the image of the subject, estimate three-dimensional facial feature location coordinates of the subject head in the image of the subject, and obtain the three-dimensional facial feature location coordinates and orientation parameters relative to a predetermined common plane;
• and compare the locations of the facial feature coordinates of the subject to the three-dimensional facial image data in the database relative to the predetermined common plane;
• whereby recognition likeness of the facial images is determined by comparing the predetermined common plane facial feature coordinates of the subject to the predetermined common plane facial feature coordinates of the images in the database.

A method of facial recognition comprising:

• inputting image data representing a plurality of images from a database;
• the database comprising images of people wherein the location of the facial features is defined relative to a predetermined common plane;
• inputting a plurality of images of a subject to be identified from at least one image sensor;
• locating predetermined three-dimensional facial features in the image of the subject for comparison to the image data from the database;
• estimating three-dimensional facial feature location coordinates of the subject head in the image of the subject;
• obtaining the three-dimensional facial feature location coordinates and orientation parameters in a coordinate system in which the facial features are located in the predetermined common plane;
• comparing the location of the coordinates of the subject to the locations of the coordinates of the images of people in the database relative to the predetermined common plane;
• and
• determining the identity of the query subject.
