Clutt3R-Seg segments objects in clutter from a few camera views. It organizes noisy masks into containment hierarchies, groups evidence across views using spatial and semantic cues, and conditionally substitutes parent masks for residual fragments. On GraspClutter6D’s difficult subset with eight views, it reaches AP@25 of 61.66 versus 27.95 for MaskClustering; this measures segmentation, not robot success or recovery of hidden objects.
