Facial Image Processing

Faces are among the most important classes of objects computers have to deal with. Consequently, automatic processing and recognition of facial images have attracted considerable attention in the last decades. In this chapter we focus on a strict view of facial image processing, i.e. transforming an input facial image into another and involving no high-level semantic classification like face recognition. A brief overview of facial image processing techniques is presented. Typical applications include removal of eyeglasses, facial expression synthesis, red-eye removal, strabismus simulation, facial weight-change simulation, caricature generation, and restoration of facial images.
