METAL: Minimum Effort Temporal Activity Localization in Untrimmed Videos

no code implementations CVPR 2020 Da Zhang, Xiyang Dai, Yuan-Fang Wang

Existing Temporal Activity Localization (TAL) methods largely adopt strong supervision for model training, which requires (1) vast amounts of untrimmed videos per each activity category and (2) accurate segment-level boundary annotations (start time and end time) for every instance.
