ZoomCount: A Zooming Mechanism for Crowd Counting in Static Images

no code implementations27 Feb 2020 Usman Sajid, Hasan Sajid, Hongcheng Wang, Guanghui Wang

This module also provides a count for each label, which is then analyzed via a specifically devised novel decision module to decide whether the image belongs to any of the two extreme cases (very low or very high density) or a normal case.

Plug-and-Play Rescaling Based Crowd Counting in Static Images

no code implementations6 Jan 2020 Usman Sajid, Guanghui Wang

Crowd counting is a challenging problem especially in the presence of huge crowd diversity across images and complex cluttered crowd-like background regions, where most previous approaches do not generalize well and consequently produce either huge crowd underestimation or overestimation.
