SF-Net: Single-Frame Supervision for Temporal Action Localization
european conference on computer vision, pp. 420-437, 2020.
In this paper, we study an intermediate form of supervision, i.e., single-frame supervision, for temporal action localization (TAL). To obtain the single-frame supervision, the annotators are asked to identify only a single frame within the temporal window of an action. This can significantly reduce the labor cost of obtaining full supe...More
