Faces are rich in information about individual identity, mood and mental state.
We now have the computing power needed to process images of faces. This presents the possibility of new ways for humans to interact with computers and computer controlled systems. Research in the area of image analysis of faces has been carried out at the Department of Medical Biophysics in collaboration with British Telecom. This work has resulted in a set of algorithms for modeling faces, which has been applied to face location, tracking of faces over a sequence of images, as well as recognition of identity, pose, gender and expression. Of particular interest is reliability across a range of facial types.
