Abstract
A method for facial recognition encode analysis comprises providing a training set of Gabor encoded arrays of face images from a database; and, for each encode array in the training set, evaluating the Gabor data to determine the accuracy of the fiducial points on which the encode array is based. The method also comprises training an outlier detection algorithm based on the evaluation of the encode arrays to obtain a decision function for a strength of accuracy of fiducial points in the encode arrays; and outputting the decision function for application to an encode array to be tested.
Claims20
A system for facial recognition encode analysis, the system comprising:
- an input/output interface configured to receive an encode array of a face image;
- and
- a processor communicatively coupled to the input/output interface, wherein the processor is configured to:
- apply, to the received encode array, a decision function resulting from training an outlier detection algorithm based on a determined accuracy of fiducial points on which a training set of Gabor encoded arrays of face images is based;
- and
- determine from a result of applying the decision function to the received encode array whether the received encode array is based on a face image with correctly identified fiducial point locations.
