PySOT

PySOT is a software system designed by SenseTime Video Intelligence Research team. It implements state-of-the-art single object tracking algorithms, including SiamRPN and SiamMask. It is written in Python and powered by the PyTorch deep learning framework. This project also contains a Python port of toolkit for evaluating trackers.

PySOT has enabled research projects, including: SiamRPN, DaSiamRPN, SiamRPN++, and SiamMask.

Example SiamFC, SiamRPN and SiamMask outputs.

Introduction

The goal of PySOT is to provide a high-quality, high-performance codebase for visual tracking research. It is designed to be flexible in order to support rapid implementation and evaluation of novel research. PySOT includes implementations of the following visual tracking algorithms:

• SiamMask
• SiamRPN++
• DaSiamRPN
• SiamRPN
• SiamFC

using the following backbone network architectures:

• ResNet{18, 34, 50}
• MobileNetV2
• AlexNet

Additional backbone architectures may be easily implemented. For more details about these models, please see References below.

Evaluation toolkit can support the following datasets:

📎 OTB2015 📎 VOT16/18/19 📎 VOT18-LT 📎 LaSOT 📎 UAV123

Model Zoo and Baselines

We provide a large set of baseline results and trained models available for download in the PySOT Model Zoo.

Installation

Please find installation instructions for PyTorch and PySOT in INSTALL.md.

Quick Start: Using PySOT

Add PySOT to your PYTHONPATH

export PYTHONPATH=/path/to/pysot:$PYTHONPATH

Download models

Download models in PySOT Model Zoo and put the model.pth in the correct directory in experiments

Webcam demo

python tools/demo.py \
    --config experiments/siamrpn_r50_l234_dwxcorr/config.yaml \
    --snapshot experiments/siamrpn_r50_l234_dwxcorr/model.pth
    # --video demo/bag.avi # (in case you don't have webcam)

Download testing datasets

Download datasets and put them into testing_dataset directory. Jsons of commonly used datasets can be downloaded from Google Drive or BaiduYun. If you want to test tracker on new dataset, please refer to pysot-toolkit to setting testing_dataset.

Test tracker

cd experiments/siamrpn_r50_l234_dwxcorr
python -u ../../tools/test.py 	\
	--snapshot model.pth 	\ # model path
	--dataset VOT2018 	\ # dataset name
	--config config.yaml	  # config file

The testing results will in the current directory(results/dataset/model_name/)

Eval tracker

assume still in experiments/siamrpn_r50_l234_dwxcorr_8gpu

python ../../tools/eval.py 	 \
	--tracker_path ./results \ # result path
	--dataset VOT2018        \ # dataset name
	--num 1 		 \ # number thread to eval
	--tracker_prefix 'model'   # tracker_name

Training 🔧

See TRAIN.md for detailed instruction.

Getting Help 🔨

If you meet problem, try searching our GitHub issues first. We intend the issues page to be a forum in which the community collectively troubleshoots problems. But please do not post duplicate issues. If you have similar issue that has been closed, you can reopen it.

• ModuleNotFoundError: No module named 'pysot'

🎯Solution: Run export PYTHONPATH=path/to/pysot first before you run the code.

• ImportError: cannot import name region

🎯Solution: Build region by python setup.py build_ext —-inplace as decribled in INSTALL.md.
