Benchmarking suite for synthetic aperture radar imagery anomaly detection (SARIAD) algorithms

Figure 1: Overall figure describing the flow of SARIAD. The figure is adapted from Anomalib for comparison.

Overview

This package is designed for anomaly detection in Synthetic Aperture Radar (SAR) images, leveraging PyTorch Lightning and models from Anomalib. The package is modular, allowing easy benchmarking and dataset integration.

Installation

Our package is on PyPI and thus can simply be installed with pip install SARIAD using python>=3.13.

Development Installation

# Clone the repository
git clone https://github.com/Advanced-Vision-and-Learning-Lab/SARIAD

# Install SARIAD in editable mode
pip install -e .

Configuration

Edit the YAML file located in config/default.yaml to specify the dataset path, model, and training parameters.

Usage

# Train with a specific configuration
python main.py --config config/default.yaml

Benchmarking

To enable benchmarking, set benchmark.enabled: True in the YAML file and specify the number of runs.

Preprocessing

• normalize.py: Functions for data normalization.
• augmentations.py: Functions for data augmentations.
• utils.py: Utility functions for SAR-specific preprocessing.

The SARDataModule located in the datasets folder imports these functions to ensure consistent preprocessing across datasets.
