CVPR 2022 (arXiv 2203.13250)

Features

• Object association within a long temporal window (32 frames).

• Classification after tracking for long-tail recognition.

• "Detector" of global trajectories.

Installation

See installation instructions.

Demo

We use the default detectron2 demo interface. For example, to run TAO model on an example video (video source: TAO/YFCC100M dataset), download the model and run

python demo.py --config-file configs/GTR_TAO_DR2101.yaml --video-input docs/yfcc_v_acef1cb6d38c2beab6e69e266e234f.mp4 --output output/demo_yfcc.mp4 --opts MODEL.WEIGHTS models/GTR_TAO_DR2101.pth

If setup correctly, the output on output/demo_yfcc.mp4 should look like:

Benchmark evaluation and training

Please first prepare datasets, then check our MODEL ZOO to reproduce results in our paper. We highlight key results below:

• MOT17 test set

MOTA	IDF1	HOTA	DetA	AssA	FPS
75.3	71.5	59.1	61.6	57.0	19.6

• TAO test set

Track mAP	FPS
20.1	11.2
