The people number estimation based on the embedded DSP system with surveillance camera

This paper proposes a method to estimate the number of the people in an indoor environment. The method is implemented on embedded digital signal processing (DSP) system for energy-saving. Using background subtraction technique to extract foreground, every row pixels of extracted foreground and an adjustable human template are weighed by the proposed weighting model and then we accumulate those weighed pixels to estimate the number of people. The experimental results show that the proposed method has outstanding performance on estimating the number of people in the video surveillance.
