Segment Anything
A promptable segmentation model from Meta that isolates objects in images or video from a point, box or text cue.
What Segment Anything is
Rather than training a segmentation model per domain, Segment Anything generalises across image types and is guided at inference by simple prompts.
How it works
An image encoder produces a reusable embedding; a lightweight decoder converts prompts into masks in real time. Video variants track masks across frames.
Why it matters
It removed most of the annotation work from segmentation projects and is widely used to accelerate dataset labelling.
