This research proposes GroupSP, a novel unsupervised deep learning approach for semantic segmentation of high-density multispectral airborne laser scanning (ALS) data, aiming to reduce manual annotation efforts while achieving comparable accuracy to supervised methods.
Advances in unsupervised learning have led to significant progress in semantic segmentation by incorporating depth information to improve feature correlation and sampling techniques.
EAGLE introduces a novel approach, emphasizing object-centric representation learning for unsupervised semantic segmentation, addressing the challenge of inadequate segmentation of complex objects with diverse structures.
