Jiaojiao Yuan, Haitao Lou, Hong Bao, Cheng Xu · 2017
For low density crowd, the statistical information of pixels and feature points can reflect the change of crowd density. Therefore, pixels and corners are fused in this paper, then, SVR is used to learn the corresponding relationship between feature and the number of people. While PSO is used to optimize the choice of parameters C and gamma in SVR. The experimental results show that the SVR optimized by PSO has better prediction accuracy.
