- R · What Makes It Special
- Meta's Segment Anything Model 2 (SAM 2, July 29, 2024), the first unified model for real-time, promptable object segmentation in images and videos, using memory to follow objects across frames at about 44 frames per second; it needs about 3x fewer interactions than earlier video methods, beats SAM on images while being 6x faster, and segments unseen objects zero-shot. Code and weights are Apache 2.0, with the SA-V dataset (about 51,000 videos); SAM 2.1 followed in fall 2024.
