✓

Library Strengths (Pros)

•60 FPS GPU hardware acceleration
•Sub-millisecond latency
•Ultra lightweight models

Trade-offs & Drawbacks (Cons)

•Requires WebGL / WebGPU context
•Occluded body parts reduce tracking accuracy

Alternative Libraries Comparison

Neutral Engineering Perspective

TensorFlow.jsAlternative

More general purpose ML vs MediaPipe's specialized vision pipelines.

Best used for: Custom model architectures.

✓ Use MediaPipe When:

•Building real-time webcam interactions or AR overlays

⚠ Consider Another Approach When:

•Training custom non-vision neural networks

Powerful Multi-Library Combinations

Future Product Architecture Ideas

🔗 MediaPipe + OpenCV.jsPipeline

MediaPipe face detection -> OpenCV privacy blur

Product Outcome: Auto face anonymizer.

Technical Limitations & Gotchas

•Low light reduces landmark stability
•WebGL context loss on mobile backgrounding
