Abstract
Crowd counting, i.e., estimation number of the pedestrian in crowd images, is emerging as an essential research problem with the public security applications. The density-based method of crowd counting still has some challenges, such as lack of perspective information in density map and background noise. Current models often misjudge background noise as a person and the ground truth density map widely used now is not so accurate. In this paper, we present a novel approach to help generate a higher quality density map. On the one hand, we eliminate the apparent mistakes in the density map with the help of a semantic segmentation model, which provides more information about fine-granted negative samples. On the other hand, we modify the density map to make sure it maintains a natural attribute. The experimental results prove the effectiveness of our method for crowd counting models, especially in uneven distribution monitoring scenario.
