Abstract
A method of estimating the number of people in crowded scenes was proposed based on energy of the foreground image in the frequency domain. Firstly, the foreground image including the target area was obtained by background subtraction. And furthermore, with the second order wavelet decomposition of the foreground image, the energy of high frequency sub-band was computed. Finally, by analyzing the relation between population size and high frequency sub-band energy, the mathematical model was established and the model was solved by the least square method. The experimental results show that the proposed method is highly effective for estimating the number of moving people in crowded scenes.
