This paper gives the hardware implementation of face detection on FPGA using Haar features. The design consisting of integral image generation which is used to compute the Haar features at a faster rate, has been illustrated. The classifiers are built using the AdaBoost algorithm which selects a minimum number of critical Haar features from a very large set. Also, parallel processing classifiers increase the speed of the face detection system by rejecting non-faces quickly. The described detection architecture has been designed using Verilog HDL and implemented on Xilinx vertex-5 FPGA which shows optimization in terms of area and speed.
