Example-based shape from shading: 3D heads form 2D face images
MetadataShow full item record
Images taken of human faces vary in perspective depending on the view point of the observer. Few of the face recognition methods reported in the literature are capable of recognising faces under varying poses. To improve the ability of face recognition systems to recognise faces under varying poses, a novel method is proposed, that takes a face image of arbitrary pose and synthesises a standard frontal pose image of the same face.
