Eigenlights: Recovering Illumination from Face Images

摘要

In this paper, we present the use of subspace modelling to find the basis features of illumination across human face images. Instead of using a real image data set we use computer-generated 3D models, which we have built. Using these models we can better investigate the effect of the recognition of faces under illumination not confined within a particular trained subset. With this we have designed a recognition system where we investigate how many training images are necessary to build an illumination subspace that gives robust recognition. We aim to apply this technique to deal with the lighting problem in face recognition on mobile devices where some current methods are simply too complex to use.
