Introduction

❗ Problem: training-testing inconsistency in recent trackers

Pitfall of frame-level training for visual tracking:
Training a tracker to better localize a target in each of individual frames of (a) does not necessarily improve actual tracking in the sequence of (b). Due to this issue, inconsistency between the validation loss and the validation performance is often observed during training as shown in (c).

✨ Solution: Sequence-Level Training (SLT)

Based on a reinforcement learning framework, SLT trains a model by actually tracking on a video and directly optimizing a tracking performance metric. Our sequence-level design of data sampling, learning objective, data augmentation boosts the generalization performance for visual tracking.

✨ Result: improvements on four baselines without modifying model architectures

Tracker (Base → Ours)	LaSOT (AUC)	TrackingNet (AUC)	GOT-10K (AO)
SiamRPN++ → SLT-SiamRPN++	51.0 → 58.4 (+7.4)	68.2 → 75.8 (+7.6)	49.5 → 62.1 (+12.6)
SiamAttn → SLT-SiamAttn	54.8 → 57.4 (+2.6)	74.3 → 76.9 (+2.6)	53.4 → 62.5 (+9.1)
TrDiMP → SLT-TrDiMP	63.3 → 64.4 (+1.1)	78.1 → 78.1 (+0.0)	67.1 → 67.5 (+0.4)
TransT → SLT-TransT	64.2 → 66.8 (+2.6)	81.1 → 82.8 (+1.7)	66.2 → 67.5 (+1.3)

Getting Started

conda install pytorch==1.10.1 torchvision==0.11.2 cudatoolkit=11.3 -c pytorch -c conda-forge

# Install requirements
pip install -r requirements.txt
sudo apt-get install libturbojpeg

# Build pycocotools
cd ${SLTtrack_ROOT}/pysot_toolkit
python setup.py build_ext --inplace

Training & Testing

• SLT-TransT and SLT-TrDiMP are implemented based on PyTracking library.
  Please refer to tutorial_pytracking.md for more details.

• SLT-SiamRPN++ and SLT-SiamAttn are implemented based on PySOT library.
  Please refer to tutorial_pysot.md for more details.
