CNN-based Density Estimation and Crowd Counting: A Survey

Understand

Accurately estimating the number of objects in a single image is a challenging yet meaningful task and has been applied in many applications such as urban planning and public safety.

• In the various object counting tasks, crowd counting is particularly prominent due to its specific significance to social security and development.
• Fortunately, the development of the techniques for crowd counting can be generalized to other related fields such as vehicle counting and environment survey, if without taking their characteristics into account.
• Therefore, many researchers are devoting to crowd counting, and many excellent works of literature and works have spurted out.
