PROTEUS
THE SHAPE-SHIFTER
Robots need to see individual objects. But labeling masks requires manual annotation. PROTEUS is a production-ready SAM 2 service — point at any object, get instant segmentation, track it through video. No training, no labels. Four model sizes from 62MB to 1.2GB. Real-time 30fps tracking on GPU.

ROBOTS CAN'T SEE OBJECT BOUNDARIES
Robots need to see individual objects. But labeling object masks requires manual annotation. Off-the-shelf segmentation fails on novel objects, tool handles, and gripper fingers. You need interactive segmentation that works on anything the first time.
Traditional approach: train on your domain, wait months, collect 10,000 labels. New approach: point at it once, SAM2 segments it, track it through video. No training. No labels. Ship it tomorrow. PROTEUS makes this production-ready.
WHAT PROTEUS DELIVERS
PROTEUS is a production-ready segmentation and tracking service built on SAM 2 (Meta AI). Accept any prompt, return masks, track through video.
PIPELINE
- 01Prompted image segmentation: point, box, mask, multi-prompt input
- 02Automatic segmentation: generate masks for all objects without prompts
- 03Real-time video tracking: mask propagation frame-by-frame at 30fps on GPU
- 04Session-based tracking state with temporal coherence
- 05Four model sizes: tiny (62MB), small (91MB), base+ (259MB), large (1.2GB)
- 06MLX Apple Silicon (M1–M5, ~60ms on M5 for small, 4x M1) + CUDA + CPU
- 07WebSocket streaming for live video + REST API + session management
CAPABILITIES
- PROMPTED SEGMENTATIONPoint, box, mask — any prompt gets instant masks→ No training needed, works on any object first time
- REAL-TIME TRACKINGFrame-by-frame mask propagation at 30fps on GPU→ Session-based state with temporal coherence across frames
- MULTI-DEVICEMLX (Apple Silicon), CUDA (GPU), CPU fallback→ Deploy on any hardware — laptop to data center
WHY THIS IS HARD
SAM2 is powerful but deployment requires careful engineering:
- 01Model sizing: four variants with 10x memory range — choosing wrong breaks production
- 02Session state management: tracking sessions must maintain frame history and mask propagation state
- 03Prompt parsing: converting user input (point at x,y) to model prompts requires calibration awareness
- 04Performance scaling: moving from batch to streaming inference changes the latency profile entirely
- 05Multi-object tracking: handling multiple simultaneous tracks without interference or ID switching
PROTEUS abstracts all of this. Initialize once per video, get frame-by-frame masks without recomputation. Production-ready session management and device abstraction.
