Perceptio: Perception Enhanced Vision Language Models via Spatial Token Generation
arXiv CS.AI
•
ArXi:2603.18795v1 Announce Type: cross Large Vision Language Models (LVLMs) excel at semantic understanding but struggle with fine grained spatial grounding, as the model must implicitly infer complex geometry without ever producing a spatial interpretation. We present Perceptio, a perception enhanced LVLM with 2D and 3D spatial reasoning abilities, enabled via explicit semantic segmentation tokens and depth tokens generated directly within the autoregressive sequence.
