Data Preparation for THUMOS14

Download Annotations

You can download the annotation by

bash download_annotation.sh

The annotation should be in data/thumos-14/annotations/.

• Following previous work such as G-TAD/VSGN, two videos are removed from the THUMOS14 validation set. (video_test_0000270 due to wrong annotations, video_test_0001292 due to empty annotations). Therefore, there are total 211 videos left in test subset. In this codebase, we use this annotation file to conduct all THUMOS-related experiments for a fair comparison.
