In order to solve the problem of miscalculation in the high and low brightness areas generated by the elliptical skin model which is proposed by Rein Lien Hsu, this paper proposed a improved method by choosing the value of long and short elliptical half shaft according to the brightness value. MATLAB Simulation experiments show that this improved algorithm has higher applicability and accuracy than the original ellipse model algorithm, also the designed system based on FPGA could meet the need of real-time face detection.
