Linear Projection Methods in Face Recognition under Unconstrained Illuminations: A Comparative Study
14 years 6 months ago
Face recognition under unconstrained illuminations (FR/I) received extensive study because of the existence of illumination subspace. [2] presented a study on the comparison betwe...
