New method fuses supervised and self-supervised learning for precise seaweed segmentation

Researchers have developed a novel two-stage method for segmenting seaweed in underwater images, crucial for blue carbon quantification and marine ecosystem monitoring. The approach combines supervised and self-supervised learning to overcome data scarcity and domain gap issues common in underwater imagery. This technique first uses supervised learning for initial class information and approximate locations, which then guides self-supervised learning for detailed segmentation, with a final refinement step using MaskFusion for highly accurate instance segmentation. The method demonstrated a significant improvement in mean Intersection over Union (mIoU) compared to existing approaches, particularly for smaller seaweed instances. AI
