Ambient Sound Helps: Audiovisual Crowd Counting in Extreme Conditions [article]

Di Hu, Lichao Mou, Qingzhong Wang, Junyu Gao, Yuansheng Hua, Dejing Dou, Xiao Xiang Zhu
2020 arXiv   pre-print
Albeit successful, vision-based crowd counting approaches could fail to capture informative features in extreme conditions, e.g., imaging at night and occlusion.  ...  In this work, we introduce a novel task of audiovisual crowd counting, in which visual and auditory information are integrated for counting purposes.  ...  Audiovision on High-quality Images Despite the success of AudioCSRNet in crowd counting under extreme conditions, here we are interested in whether ambient sounds help when high-quality images are available  ...

Audio-visual Representation Learning for Anomaly Events Detection in Crowds [article]

Junyu Gao, Maoguo Gong, Xuelong Li
2021 arXiv   pre-print
However, when an abnormal event in crowds occurs, sound information may be discriminative to assist the crowd analysis system to determine whether there is an abnormality.  ...  In recent years, anomaly events detection in crowd scenes attracts many researchers' attention, because of its importance to public safety.  ...  The method significantly reduces the estimation errors for crowd counting in extreme conditions.  ...

Advances in Convolution Neural Networks Based Crowd Counting and Density Estimation

Rafik Gouiaa, Moulay A. Akhloufi, Mozhdeh Shahbazi
2021 Big Data and Cognitive Computing  
Many challenges and problems face crowd counting, including cluttered scenes, extreme occlusions, scale variation, and changes in camera perspective.  ...  The significant progress in crowd counting methods in recent years is mostly attributed to advances in deep convolution neural networks (CNNs) as well as to public crowd counting datasets.  ...  Crowd counting remains a challenging task due to different difficulties related to the unconstrained scenes, such as extreme occlusions, variation in light conditions, changes in scale and camera perspective  ...
