Robust Long-Term Object Tracking via Improved Discriminative Model Prediction (RLT-DIMP) [ECCVW2020 paper]
1-minute version (ENG)
12-minute version (ENG)
We propose an improved discriminative model prediction method for robust long-term tracking based on a pre-trained short-term tracker. The baseline pre-trained short-term tracker is SuperDiMP which combines the bounding-box regressor of PrDiMP with the standard DiMP classifier. Our tracker RLT-DiMP improves SuperDiMP in the following three aspects: (1) Uncertainty reduction using random erasing: To make our model robust, we exploit an agreement from multiple images after erasing random small rectangular areas as a certainty. And then, we correct the tracking state of our model accordingly. (2) Random search with spatio-temporal constraints: we propose a robust random search method with a score penalty applied to prevent the problem of sudden detection at a distance. (3) Background augmentation for more discriminative feature learning: We augment various backgrounds that are not included in the search area to train a more robust model in the background clutter. In experiments on the VOT-LT2020 benchmark dataset, the proposed method achieves comparable performance to the state-of-the-art long-term trackers.
- We adopt the pre-trained short-term tracker which combines the bounding box regressor of PrDiMP with the standard DiMP classifier
- This tracker's name is SuperDiMP and it can be downloaded on the DiMP-family's github page [link]
- Ubuntu 18.04 / Python 3.6 / CUDA 10.0 / gcc 7.5.0
- Need anaconda
- Need GPU (more than 2GB, Sometimes it is a little more necessary depending on the situation.)
- Unfortunately, "Precise RoI Pooling" included in the Dimp tracker only supports GPU (cuda) implementations.
- Need root permission
- All libraries in “install.sh” file (please check “how to install”)
- Unzip files in
$(tracker-path) - cd
$(tracker-path) - bash install.sh
$(anaconda-path)$(env-name)(Automatically create conda environment, If you don’t want to make more conda environments, run “bash install_in_conda.sh” after conda activation) - check pretrained model "super_dimp.pth.tar" in
$(tracker-path)$/pytracking/networks/(It should be downloaded by install.sh) - conda activate
$(env-name) - make VOTLT2020 workspace (vot workspace votlt2020 --workspace
$(workspace-path)) - move trackers.ini to
$(workspace-path) - move(or download) votlt2020 dataset to
$(workspace-path)/sequences - set the VOT dataset directory (
$(tracker-path)/pytracking/evaluation/local.py), vot_path should include ‘sequence’ word (e.g.,$(vot-dataset-path)/sequences/), vot_path must be the absolute path (not relative path) - modify paths in the trackers.ini file, paths should include ‘pytracking’ word (e.g.,
$(tracker-path)/pytracking), paths must be absolute path (not relative path) - cd
$(workspace-path) - vot evaluate RLT_DiMP --workspace
$(workspace-path) - It will fail once because the “precise rol pooling” file has to be compiled through the ninja. Please check the handling error parts.
- vot analysis --workspace
$(workspace-path)RLT_DiMP --output json
- “Process did not finish yet” or “Error during tracker execution: Exception when waiting for response: Unknown”-> re-try or “sudo rm -rf
/tmp/torch_extensions/_prroi_pooling/” - About “groundtruth.txt” -> check vot_path in the
$(tracker-path)/pytracking/evaluation/local.pyfile - About “
pytracking/evaluation/local.py” -> check and run install.sh - About “permission denied : “
/tmp/torch_extensions/_prroi_pooling/” -> sudo chmod -R 777/tmp/torch_extensions/_prroi_pooling/ - About “No module named 'ltr.external.PreciseRoiPooling’” or “can not complie Precise RoI Pooling library error” -> cd
$(tracker-path)-> rm -rf/ltr/external/PreciseRoiPooling-> git clone https://github.com/vacancy/PreciseRoIPooling.gitltr/external/PreciseRoIPooling - If nothing happens since the code just stopped -> sudo rm -rf
/tmp/torch_extensions/_prroi_pooling/
