| # Data Preparation for THUMOS14 | |
| ## Download Annotations | |
| You can download the annotation by | |
| ```bash | |
| 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. | |
