Adaptive Scenario Discovery for Crowd Counting
This addresses public security applications by improving crowd counting robustness, but it appears incremental as it builds on existing methods with adaptive enhancements.
The paper tackles the problem of robust crowd counting across diverse scenarios by introducing an adaptive scenario discovery framework with parallel pathways and a recalibration branch, achieving state-of-the-art results on two benchmarks.
Crowd counting, i.e., estimation number of the pedestrian in crowd images, is emerging as an important research problem with the public security applications. A key component for the crowd counting systems is the construction of counting models which are robust to various scenarios under facts such as camera perspective and physical barriers. In this paper, we present an adaptive scenario discovery framework for crowd counting. The system is structured with two parallel pathways that are trained with different sizes of the receptive field to represent different scales and crowd densities. After ensuring that these components are present in the proper geometric configuration, a third branch is designed to adaptively recalibrate the pathway-wise responses by discovering and modeling the dynamic scenarios implicitly. Our system is able to represent highly variable crowd images and achieves state-of-the-art results in two challenging benchmarks.
