Installation

pip install -U datasouls_antispoof

Example inference

Colab notebook with the example:

Dataset

ID & RD anti spoofing challenge

Four types of images:

• real
• replay
• printed
• mask2d

Training

Define the config.

Example at datasoluls_antispoof/configs

Define the environmental variable IMAGE_PATH that points to the folder with the dataset.

Example:

export IMAGE_PATH=<path to the folder with images>

Inference

python -m torch.distributed.launch --nproc_per_node=<num_gpu> datasouls_antispoof/inference.py \
                                   -i <path to images> \
                                   -c <path to config> \
                                   -w <path to weights> \
                                   -o <output-path> \
                                   --fp16
