(57) Abstract :
A 3D face reconstruction technique using 2D images, such as photograpns of a race, is described. Prior face knowledge or a generic
face is used to extract sparse 3D information from the images and to identify image pairs. Bundle adjustment is carried out to
determine more accurate 3D camera positions, image pairs are rectified, and dense 3D face information is extracted without using the
prior face knowledge. Outliers are removed, e.g., by using tensor voting. A 3D surface is extracted from the dense 3D information and
surface detail is extracted from the images.
