Abstract
Image-based 3D face reconstruction techniques can be used for generating a 3D model of a person’s face given a single or multiple
images of the face of a person. Such techniques could be used for generating 3D models of faces appearing in cultural heritance
artefacts, based on images captured with ordinary digital cameras. The ability to generate 3D reconstructions of faces appearing in
cultural heritage artefacts will facilitate the development of numerous applications such as the generation of cultural heritage related
3D animations, short films, educational applications and customized educational games. In this paper we review key image-based
3D face reconstruction algorithms belonging to different categories and assess their applicability for reconstructing 3D faces
appearing in cultural heritage artefacts. We also describe a dedicated 3D face reconstruction algorithm that can be used for efficient
reconstruction of faces in cultural heritage applications based on a single image. The proposed algorithm requires the location of a
number of landmarks on the face to be reconstructed. A deformable 3D shape model is used for generating an approximation of the
3D face geometry of the face shown on the artefact and texture mapping is used for generating the full 3D model. In the paper we
present initial quantitative results and visual results obtained when the method was used for reconstructing 3D faces appearing in
different types of cultural heritage artefacts such as statues, paintings, murals and mosaics.
