Patent ID: 8509561

Claim:
A method of determining a characteristic of a face or certain other object within a scene captured in a digital image, comprising: (a) acquiring a digital image including a face or certain other object within a scene; (b) applying a linear texture model that is constructed based on a training data set and that comprises a combination of orthogonal directional and directionally-independent subspaces respectively constructed from a class of objects including a first subset of model components that exhibit a dependency on directional lighting variations and a second subset of model components which are independent of directional lighting variations; (c) determining an initial location of the face or certain other object in the scene; (d) obtaining a fit of said model to said face or certain other object including adjusting one or more individual values of one or more of the model components of said linear texture model; (e) based on the obtained fit of the model to said face or certain other object in the scene, determining at least one characteristic of the face or certain other object; and (f) electronically storing, transmitting, applying a face or other object recognition program to, editing, or displaying the corrected face image or certain other object including the determined characteristic, or combinations thereof.
