ALinear Transformation Model on Face Image and ItsApplication in Recognition
Chong Zhang · Acta Simulata Systematica Sinica · 2005
Under different illumination conditions, image on an individual may vary dramatically, as a result face recognition becomes more difficult because of this factor. In this paper, a linear transformation model on face image is proposed. The model is feasible, simple and tractable in computing. Moreover, it is very effective to weaken the aftereffect of varying illumination. To illustrate the application on the model, experiments are performed on YaleB and AR face image databases.
