Overview

Randomized trial evaluates deep learning models for marine pollution detection using satellite imagery, suggesting improved monitoring methods.

Key Points

This study aims to enhance detection methods for marine pollutants using deep learning on satellite imagery.
Constructed a new Sentinel-1 SAR dataset with annotations for various marine pollutants.
Trained deep learning models including U-NET, MARINEXT, and SEGNEXT on this dataset.
Evaluated model performance quantitatively with F1-macro scores and qualitatively with Sentinel-2 imagery.
MARINEXT achieved the highest F1-macro score of 92.7%, outperforming U-NET at 70.6% and SEGNEXT at 75.9%.
Qualitative evaluations align with quantitative findings, showing effective results for oil spill and ship detection.
Mapping marine debris proved challenging when corresponding optical observations were unavailable.
