CSA

Dataset

Data preperation

We use PLA as baseline and we aims to refine its detection results. Please obtain its detection results as described in their repo and put it into CSA/data/action-genome folder.

Besides, you can download our preprocessed detection results, pretrained checkpoint and other necessary files in this link, and then put them in corresponding location.

The directories of CSA should look like:

|-- data
    |-- action-genome
        |-- frames        # sampled frames
        |-- videos        # original videos
        |-- AG_detection_results # detection results as PLA described
        |-- annotations   # downloaded gt annotations
        |-- AG_detection_results_refine # downloaded preprocessed refine detection results
|-- refine
    |-- output # downloaded checkpoint
    |-- ...
|-- PLA
    |-- model # downloaded checkpoint
    |-- ...

Evaluation

• For refine model

cd ~/CSA/refine
python scripts/evaluate.py # evaluate the performance of object detection

AP@1	AP@10	AR@1	AR@10	weight
13.8	14.2	35.2	40.6	link

• For preprocess (optional)

You can obtain the detection results with trained model. The split to be inferred should be given in preprocess.py, which is in ['test', 'train', 'total']. These three splits should all be processed.

cd ~/CSA/refine
python scripts/preprocess.py

• For PLA model

cd ~/CSA/PLA
python test.py --cfg configs/oneframe.yml # for image SGG model
python test.py --cfg configs/final.yml # for video SGG model

Model	W/R@10	W/R@20	W/R@50	N/R@10	N/R@20	N/R@50	weight
Image	16.52	21.42	26.68	17.57	23.35	32.27	link
Video	16.83	21.72	26.96	17.95	23.98	32.98	link

Train

• For refine model

cd ~/CSA/refine
python scripts/train.py # evaluate object detection results

• For PLA model

cd ~/CSA/PLA
python train.py --cfg configs/oneframe.yml # for image SGG model
python train.py --cfg configs/final.yml # for video SGG model
