SIG-Net: A Spectral-Index-Guided Network for Red Tide Extraction from Sentinel-2 Multispectral Imagery

Red tide events pose substantial threats to marine ecosystems, aquaculture, and coastal public health. Timely and accurate delineation of red tide extent from satellite imagery is therefore essential for operational monitoring and early warning. However, existing deep learning-based semantic segment...
