English(EN) To Remove or Not to Remove Clouds: A Comparative Analysis and Fusion of Raw SAR and Synthetic NDWI for Overcast Water Segmentation

新研究融合SAR和合成NDWI以改进阴天水体分割

作者 PulseAugur 编辑部 · [1 个来源] · 2026-08-19 04:00

一篇新研究论文探讨了从卫星图像中分割水体的方法，特别是在光学卫星受阻的阴天条件下。该研究比较了直接使用原始合成孔径雷达（SAR）数据与使用深度学习生成的合成归一化水体指数（NDWI）。研究结果表明，合成NDWI方法因其噪声过滤能力而更优越。此外，该论文还提出了一种结合框架，融合了原始SAR和合成NDWI，通过利用各自的优势实现了更好的性能。 AI

影响这项研究可以提高卫星图像中水体检测的准确性，有助于灾害响应和环境监测。

移除还是不移除云层：原始SAR和合成NDWI用于阴天水体分割的比较分析与融合

arXiv:2608.17398v1 Announce Type: new Abstract: Persistent clouds blind optical satellites during floods. While Synthetic Aperture Radar (SAR) penetrates clouds, its raw data is noisy and lacks clear contrast. To mitigate this, recent studies utilize deep learning models to trans…
