VOT-LT test instructions

To run the VOT Challenge Long-term experiments please follow these instructions:

• Clone the repository git clone https://github.com/matteo-dunnhofer/CoCoLoT

• Download the pre-trained weights files STARKST_ep0050.pth.tar, super_dimp.pth.tar, metric_model.pt from here and put them in the folder CoCoLoT/ckpt/

• Move to the submission source folder cd CoCoLoT

• Create the Anaconda environment conda env create -f environment.yml

• Activate the environment conda activate CoCoLoT

• Install ninja-build sudo apt-get install ninja-build

• Edit the variable base_path in the file vot_path.py by providing the full-path to the location where the submission folder is stored, and do the same in the file trackers.ini by substituting the paths [full-path-to-CoCoLoT] in line 9 and 13

• Run python compile_pytracking.py

• Run the analysis by vot evaluate CoCoLoT

• Run the evaluation by vot analysis CoCoLoT

If you fail to run our tracker please write to matteo.dunnhofer@uniud.it

An improved version of CoCoLoT (submitted to the VOT2022 Challenge) exploiting Stark and KeepTrack is downloadable here.
