Updates

• [8/19/2023] Code of HSTforU is released (with password). We will remove the password after this paper is accepted.

Setup

The code can be run under any environment with Python 3.7 and above. (It may run with lower versions, but we have not tested it).

Install the required packages:

pip install -r requirements.txt

Clone this repo:

git clone https://github.com/vt-le/HSTforU.git
cd HSTforU/

We evaluate HSTforU on:

Evaluation

Please first download the pre-trained model

Dataset	Pretrained Model
UCSD Ped2
CUHK Avenue
ShanghaiTech
Drone-Anomaly

To evaluate a pretrained HSTforU on a dataset, run:

 python test.py \
    --cfg <path/to/config/file> \
    --pretrained </path/to/pre-trained/model> \
    [--batch-size <batch-size> --tag <job-tag>]

For example, to evaluate HSTforU on Ped2:

python test.py \
    --cfg config/scripts/ped2/ped2_pvt2_hst.yaml \
    --model-file output/HSTforU/ped2_pvt2_hst/ckpt_ped2.pth

Configuration

• We use YAML for configuration.
• We provide a couple preset configurations.
• Please refer to config.py for documentation on what each configuration does.
