An embedded face recognition system on A VLSI array architecture and its FPGA implementation

Face recognition is a non-intrusive way of automated person identification. A popular method for face recognition is using eigen faces. Eigen faces are obtained by doing principal component analysis (PCA) on the face database. A neural network that performs PCA is called principal component neural network (PCNN). This paper presents a systolic array design for principal component neural network-based face recognition system. Results of implementation of the design in an FPGA device of Xilinx confirm the suitability of the design for real-time video surveillance and high-speed access control.
