SAM2 Tiny (Cell and Bacterium Tracking)
The SAM2 tiny checkpoint used in the Model Garden Cell and Bacterium Tracking demo: class-agnostic video segment-and-track where pretrained detectors have no labels, e.g. a neutrophil chasing a bacterium.
Method
Human-seed-then-propagate: a few clicks lock the right object, then SAM2 propagates masks across the rest of the frames autonomously. No training required.
Provenance
This is the sam2_hiera_tiny checkpoint from
facebook/sam2-hiera-tiny,
re-hosted here for the Model Garden showcase. All credit to Meta AI.
Usage
