Locality and Relative Distance-Aware Non-local Networks for Hand-Raising Detection in Classroom Video
2021 International Conference on Multimedia Analysis and Pattern Recognition (MAPR)(2021)
摘要
Detecting and understanding interactions between students and teachers in classroom is an important criterion for computer vision-based educational assistive systems. Recently, deep long-range spatial dependencies modeling techniques, such as non-local networks, have been proven to be very effective for such tasks. Yet, regarding global context generation, we analyze that the non-local operation o...
