System and method for face recognition robust to multiple degradations
First Claim
Patent Images
1. A system for correcting for degradations in a 2D image of a face captured with an image sensor, comprising:
- a computing device executing software for performing the functions of;
(a) placing a plurality of fiducial points at landmarks on said face, each of said fiducial points corresponding to a fiducial point for a mean face calculated over a database set of faces;
(b) calculating a function which captures the deviation of each fiducial point from said mean fiducial point;
(c) using a thin-plate spline function to create a test face by minimizing a function which provides a measure of the smoothness of the function calculated in step (b);
(d) selecting a set of uniformly-distributed points on said mean face; and
(e) finding a set of points on said test face corresponding to said uniformly-distributed set of points on said mean face.

Abstract
A novel, unified technique for analyzing, synthesizing, and recognizing faces captured by various modalities, and under a variety of often seen real-world circumstances, using thin-plate splines for densification of points of a face from an initial set of fiducial points.
