| Abstract(in English) | The virtual subspace is proposed for realizing a robust face recognition free with the lighting conditions. The virtual subspace is a paradoxical concept because it can be constructed even if only one image is taken. Furthermore, the virtual subspace is gradually converged to the real subspace when face images are subsequently taken. Composition of the virtual subspace is based on eigenspace analysis (principal component analysis) of synthesized virtual images, which are supposed to be taken in a variety of lighting conditions. For synthesizing a virtual image, we use a canonical eigenspace which is readily constructed from a set of face images which includes a lot of persons, each in a lot of different lighting conditions. A lighting estimation and a lighting compensation algorithms are proposed using the canonical eigenspace. The virtual subspace is defined as an eigenspace composed from the synthesized image set. Experimented results are also provided. |
