WebFurther, there is a need of development of real-time biometric system. There exist many graph matching techniques used to design robust and real-time biometrics systems. This paper discusses two graph matching techniques that have been successfully used in face biometric traits. Keywords. Biometrics; Graphs; SIFT features; Face recognitions
WebEach face is bounded by a closed walk called the boundary of the face. By convention, we also count the unbounded area outside the whole graph as one face. The degree of the face is the length of its boundary. For example, in the figure below, the lefthand graph has three faces. The boundary of face 2 has edges df,fe,ec,cd, so this face has ...
