One Click per Cell Type Suffices: Training-free Group Interaction for Cell Instance Segmentation
arXiv CS.CV

ArXi:2605.29429v1 Announce Type: new Cell instance segmentation models trained on cell-specific datasets suffer severe performance drops on out-of-distribution cell types, while interactive foundation models overcome this through per-instance prompting at a cost that is prohibitively expensive for histopathology images containing hundreds to thousands of densely packed instances. We
