TARGET-GUIDED LEARNING FOR RARE CLASS SEGMENTATION IN LARGE-SCALE URBAN POINT CLOUDS
In large-scale urban areas, the diversity of objects and the complexity of scenes pose challenges to semantic segmentation of point clouds. In particular, the data imbalance problem often results in poor performance for rare classes in large scenes. This paper proposes a rare class segmentation meth...
