Temporal Action Detection

We use the ActionFormer detection pipeline as our baseline method and replace its I3D feature with the feature extracted by VideoMAE V2-g.

Dataset	Backbone	Head	mAP	Features
THUMOS14	VideoMAE V2-g	ActionFormer	69.6	th14_mae_g_16_4.tar.gz
FineAction	VideoMAE V2-g	ActionFormer	18.2	fineaction_mae_g.tar.gz

Extract feature

Use extract_tad_feature.py to extract the feature of datasets. For example, to extract the feature of THUMOS14, running the following command:

python extract_tad_feature.py \
    --data_set THUMOS14 \
    --data_path YOUR_PATH/thumos14_videos \
    --save_path YOUR_PATH/th14_vit_g_16_4 \
    --model vit_giant_patch14_224 \
    --ckpt_path YOUR_PATH/vit_g_hyrbid_pt_1200e_k710_ft.pth
