APPARATUS AND METHOD FOR ROBUST FACE RECOGNITION VIA HIERARCHICAL COLLABORATIVE REPRESENTATION

摘要

The present invention relates to a robust face recognition apparatus through classification based on hierarchical collaborative expression, and to a method thereof. The robust face recognition apparatus through classification based on hierarchical collaborative expression can accurately perform face recognition without being affected by noise and lighting effects through the hierarchical collaboration representation classification considering a Euclidean distance between a face image for the face recognition in a collaboration subspace of learning data and a projection vector for the face image and a Euclidean distance from the projection vector to the learning vector with respect to the learning data.
