AI framework maps seagrass habitats using sonar imagery with weak supervision

Researchers have developed a weakly supervised semantic segmentation framework to map seagrass habitats using side-scan sonar imagery. This method learns pixel-level maps from image-level labels alone, employing a Vision Transformer (ViT)-based encoder-decoder and a classification branch. The framework refines pseudo-labels using a dense conditional random field and an iterative self-training scheme to handle class imbalance and noise. Experiments showed that the Lovász-Softmax loss function was most effective, and the model achieved an mIoU of 87.6% without pixel-level labels, with self-supervised pretraining further improving performance. AI

    Weakly Supervised Seafloor Segmentation for Seagrass Habitat Mapping in Side-Scan Sonar Imagery

    arXiv:2608.24756v1 Announce Type: cross Abstract: Seagrass meadows are crucial blue-carbon habitats, and mapping their extent is a prerequisite for coastal management and carbon inventory. Optical satellite sensors cover large areas but cannot reach deep or turbid water, whereas …
