AnchorSeg: Language Grounded Query Banks for Reasoning Segmentation

arXiv CS.CV

ArXi:2604.18562v1 Announce Type: new Reasoning segmentation requires models to ground complex, implicit textual queries into precise pixel-level masks. Existing approaches rely on a single segmentation token $\texttt{}$, whose hidden state implicitly encodes both semantic reasoning and spatial localization, limiting the model's ability to explicitly disentangle what to segment from where to segment. We
