Researchers have developed a novel weakly supervised semantic segmentation framework for mapping coral habitats using drone imagery. This method effectively trains high-resolution segmentation models by combining fine-scale classification data with broader aerial imagery, converting point-level classifications into supervision masks. The framework achieves significant accuracy, with 86.07% pixel accuracy and 52.23% mIoU on manually annotated reef zones, without requiring pixel-level annotations. AI
