Meta’s Segment Anything Model 2 (SAM 2) delivers real-time, unified mask generation for 3D spatio-temporal data and video point clouds.

SAM 2 expands the original Segment Anything capabilities into the third dimension by treating video as a continuous 3D spatio-temporal entity. It utilizes a streaming memory architecture (storing feature memories and object pointers) to track masks across frames with high precision. In benchmark tests, SAM 2 outperforms previous models using 3x less interaction time while maintaining 80+ frames per second performance. This technology enables developers to segment 3D volumes in medical imaging or track dynamic objects in robotics via simple point, box, or mask prompts.

## Recent Public Talks and Demos

### [Reconstructing Memories with 3D Gaussian Splatting](https://hong-kong.aitinkerers.org/talks/rsvp_zmGEdhKSUks)

The Foundation: Using 3D Gaussian Splatting (3DGS) to recreate real-world environments with hyper-realistic fidelity with PostShot. Showing the PLY file on SuperSplat also showing how ply file structure. Meta SAM 3D: Integrating Meta’s SAM 3D to isolate and create specific 3D objects. Also showing the Spatial Reasoning ability and when it fails. Apple’s SHARP: Using Apple’s SHARP via CLI to transform flat, historical photos into 3D Gaussian volumes, effectively "re-spatializing" the past. Custom code for batch processing and potentially 4D gaussian splatting creation. Marble (World Labs): Implementing Marble (World Labs) to generate synthetic 3D environments that reflects subjective imagination.
