Temporal action localization (TAL) in untrimmed videos recently receives tremendous research enthusiasm. To our best knowledge, this is the first attempt literature to explore task under an unsupervised setting, hereafter referred as co-localization (ACL), where only total count of unique actions that appear video set known. solve ACL, we propose a two-step ``clustering + localization" iterative procedure. The clustering step provides noisy pseudo-labels for step, and temporal co-attention...
Video visual relation detection (VidVRD) aims to describe all interacting objects in a video. Different from relationships static images, videos contain an addition temporal channel. A majority of existing works divide video into short segments, predict each segment, and merge them. Such methods cannot capture relations involving long motions. Predicting the same relationship across neighboring segments is also inefficient. To address these issues, this work proposes novel sliding-window...
