SAM 3: Segment Anything with Concepts
arXiv CS.AI
•
ArXi:2511.16719v2 Announce Type: replace-cross We present Segment Anything Model (SAM) 3, a unified model that detects, segments, and tracks objects in images and videos based on concept prompts, which we define as either short noun phrases (e.g., "yellow school bus"), image exemplars, or a combination of both. Promptable Concept Segmentation (PCS) takes such prompts and returns segmentation masks and unique identities for all matching object instances.
