Highlights
✨ Efficient Fully Transformer Tracking Framework
MixFormerV2 is a well unified fully transformer tracking model, without any dense convolutional operation and complex score prediction module. We propose four key prediction tokens to capture the correlation between target template and search area.
✨ A New Distillation-based Model Reduction Paradigm
To further improve efficiency, we present a new distillation paradigm for tracking model, including dense-to-sparse stage and deep-to-shallow stage.
✨ Strong Performance and Fast Inference Speed
MixFormerV2 works well for different benchmarks and can achieve 70.6% AUC on LaSOT and 57.4% AUC on TNL2k, while keeping 165fps on GPU. To our best knowledge, MixFormerV2-S is the first transformer-based one-stream tracker which achieves real-time running on CPU.
Install the environment
Use the Anaconda
conda create -n mixformer2 python=3.6
conda activate mixformer2
bash install_requirements.sh
Data Preparation
Put the tracking datasets in ./data. It should look like:
${MixFormerV2_ROOT}
-- data
-- lasot
|-- airplane
|-- basketball
|-- bear
...
-- got10k
|-- test
|-- train
|-- val
-- coco
|-- annotations
|-- train2017
-- trackingnet
|-- TRAIN_0
|-- TRAIN_1
...
|-- TRAIN_11
|-- TEST
Set project paths
Run the following command to set paths for this project
python tracking/create_default_local_file.py --workspace_dir . --data_dir ./data --save_dir .
After running this command, you can also modify paths by editing these two files
lib/train/admin/local.py # paths about training
lib/test/evaluation/local.py # paths about testing
Train MixFormerV2
Training with multiple GPUs using DDP. More details of other training settings can be found at tracking/train_mixformer.sh
.
bash tracking/train_mixformer.sh
Test and evaluate MixFormerV2 on benchmarks
- LaSOT/GOT10k-test/TrackingNet/OTB100/UAV123/TNL2k. More details of test settings can be found at
tracking/test_mixformer.sh
.
bash tracking/test_mixformer.sh
TODO
- Progressive eliminating version of training.
- Fast version of test forwarding.
