MINI-Net: Multiple Instance Ranking Network for Video Highlight Detection [article]

Fa-Ting Hong, Xuanteng Huang, Wei-Hong Li, Wei-Shi Zheng
2020 arXiv   pre-print
We address the weakly supervised video highlight detection problem for learning to detect segments that are more attractive in training videos given their video event label but without expensive supervision  ...  In this work, we propose casting weakly supervised video highlight detection modeling for a given specific event as a multiple instance ranking network (MINI-Net) learning.  ...  The second strategy treats video highlight detection as a weakly supervised recognition task [34, 31, 29] .  ...

Visual Social Relationship Recognition [article]

Junnan Li, Yongkang Wong, Qi Zhao, Mohan S. Kankanhalli
2018 arXiv   pre-print
Since visually identifying social relationship bears certain degree of uncertainty, we further propose an Adaptive Focal Loss to leverage the ambiguous annotations for more effective learning.  ...  We propose a Dual-Glance model for social relationship recognition, where the first glance fixates at the person of interest and the second glance deploys attention mechanism to exploit contextual cues  ...  For group activity recognition, social roles and relationship information have been implicitly embedded into the inference model (Choi and Savarese 2012; Deng et al 2016; Direkoglu and O'Connor 2012; Lan  ...
