Highlighted rows are where these differ.
SAM 2
- Not a detector: it segments what you point at
- Transformed how detection datasets get labelled
Best for segmentation and annotation.
RTMDet
- Wins on raw speed where accuracy is sufficient
- MIT, so no derivative-work obligation
Best for high frame-rate video.
