Conference paper


This paper describes a novel face recognition method, the orthoface method. The method is efficient and invariant to variation in lighting conditions, facial expressions and alien objects. At the centre of the orthoface method is a set of basis vectors named the orthofaces. Orthofaces are more effective basis vectors from a discrimination viewpoint because each of them accounts for the individual features of a training face. We will explain the logic behind the orthoface method. We will also justify with both mathematical reasoning and experimental results why the orthoface method is the method that leads to effective classification strategies.
