Abstract
This invention concerns computer based face recognition. A person's face is captured in an image and received (12) by a computer (30). The computer operates to estimate the orientation of the face (14). Then using a correlation model, the pose effect is removed from the image that is now represented as pose independent features (16). Pattern recognition techniques are then applied (18) to compare the pose independent features to a gallery stored in memory (18) to match the face to a member of the gallery. The invention offers greater accuracy and can be performed in real time. Aspects of the invention includes a method, software and a computer system.
Claims12
A method for face recognition, comprising the steps of:
- receiving an image including a face in a pose;
- performing an Active Appearance Model (AAM) search on the image to estimate the orientation of the face;
- applying a correlation model to remove a pose effect and representing the face as pose independent features;
- then,
- applying pattern recognition techniques to compare the pose independent features to a gallery to match the face to a member of the gallery.
A computer system to perform facial recognition comprising:
- input means to receive an image of a face in a pose;
- memory to store a gallery of faces;
- a processor operable to perform an Active Appearance Model (AAM) search on the image to estimate the orientation of the face, to apply a correlation model to remove a pose effect and to represent the face as pose independent features, and to apply pattern recognition techniques to compare the pose independent features to the gallery to match the face to a member of the gallery.
