What It Does

  • +High-accuracy two-stage object detection (Faster R-CNN, Cascade R-CNN)
  • +State-of-the-art instance and panoptic segmentation (Mask R-CNN, PointRend)
  • +DensePose 3D surface mapping on human bodies
  • +Modular configuration system using yacs and fvcore

What It Does Not Do

  • -Natively export to ONNX without custom C++ op registration
  • -Run at real-time speeds on battery-powered mobile edge processors
  • -Receive frequent active feature updates (largely in maintenance mode)

>Suitable Work Types

  • High-precision document layout analysis (detecting tables, headers, signatures)
  • Medical tissue and pathology segmentation
  • Academic computer vision research benchmarks

>Unsuitable Work Types

  • Sub-10ms real-time edge video streaming (use YOLO or TensorRT)
  • Web browser client-side execution
Data Residency Implications

Operates entirely locally in memory. Zero external calls.

Security Considerations

Ensure build environment uses trusted CUDA compilers and dependencies.

Operational Profile & Known Limitations

Maturity:mature
Learning Curve:high
Ops Complexity:high
Cost Tier:free-oss
> Known Limitations:
  • Maintenance velocity has slowed in recent years; installation frequently conflicts with modern PyTorch/CUDA builds due to C++ extensions.
