An architectural hardware scheme for the generation of LG graphs for real-time image analysis

This paper presents a hardware architecture scheme that implements the local-global (LG) graph methodology. The LG graph method has the capability to efficiently represent the context of a segmented image and hold its structure independent to rotation, translation and scaling. The LG graph method has been successfully used on object/pattern recognition, image understanding, face/facial expression recognition, biometrics representation and recognition.
