SkeleVision: Towards Adversarial Resiliency of Person Tracking with Multi-Task Learning
Nilaksh Das, Sheng-Yun Peng, Duen Horng Chau

Quickstart

$ make venv
$ make armory_configure
$ CUDA_VISIBLE_DEVICES=0,1,2,3 make \
    attack~carla~finetune-MTL-lambda_k_0.2~eps_step_0.2~max_iter_100

Setup

$ make venv
$ make armory_configure

Training Data

$ make training_data

NOTE: We have automated the process for downloading the training data, but due to throttling limitations of Google Drive that are beyond our control, you MAY have to manually download the LaSOT dataset split (person.zip) from this link and place it in the data/ directory.

Model Training

First, you will need to download the pre-trained SiamRPN weigths.

$ make pretrained_siamrpn

Next, running the following command will train the model and save it to experiments/models/train/<MODEL_NAME>

$ CUDA_VISIBLE_DEVICES=0,1,2,3 make <MODEL_NAME>

Model Names

The MTL models are suffixed with the MTL weight (lambda_k).

# STL
finetune-STL

# MTL
finetune-MTL-lambda_k_0.2
finetune-MTL-lambda_k_0.4
finetune-MTL-lambda_k_0.6
finetune-MTL-lambda_k_0.8
finetune-MTL-lambda_k_1.0

# MTL Ablation: deep
finetune-MTL-deep-lambda_k_0.2
finetune-MTL-deep-lambda_k_1.0

# MTL Ablation: pretrained keypoint head
finetune-MTL-pretrain_keypoint_head-lambda_k_0.2
finetune-MTL-pretrain_keypoint_head-lambda_k_1.0

# MTL Ablation: deep + pretrained keypoint head
finetune-MTL-pretrain_keypoint_head-deep-lambda_k_0.2
finetune-MTL-pretrain_keypoint_head-deep-lambda_k_1.0

Adversarial Attack

Running the following command will perform an adversarial attack and save the results at:

experiments/adversarial/<DATASET_NAME>-<MODEL_NAME>-eps_step_<STEP_SIZE>-max_iter_<NUM_ITERS>.armory_run_<TIMESTAMP>

$ CUDA_VISIBLE_DEVICES=0,1,2,3 make \
    attack~<DATASET_NAME>~<MODEL_NAME>~eps_step_<STEP_SIZE>~max_iter_<NUM_ITERS>

Dataset Names

  • carla
  • otb

Attack examples

$ CUDA_VISIBLE_DEVICES=0,1,2,3 make \
    attack~carla~finetune-MTL-lambda_k_0.2~eps_step_0.2~max_iter_100

$ CUDA_VISIBLE_DEVICES=0,1,2,3 make \
    attack~carla~finetune-MTL-deep-lambda_k_1.0~eps_step_0.1~max_iter_50

$ CUDA_VISIBLE_DEVICES=0,1,2,3 make \
    attack~otb~finetune-MTL-lambda_k_0.4~eps_step_0.2~max_iter_20

NOTE: If you have not downloaded the training data and the pre-trained model, or trained the model being attacked, running the above examples will do all of that before performing the adversarial attack.
