What the engine does
- Detect and track the face and select skin regions.
- Extract temporal color signals from the camera frames.
- Filter the signal and estimate beats per minute.
- Visualize the pulse signal and estimated heart rate.
Where it fits
For engineers and researchers studying camera-based physiological signal processing. Inspect the C++ implementation and evaluate the effect of your camera, lighting and processing choices.
What to validate before you buy
For technical demonstration and education only. This is not a medical device and must not be used for diagnosis or health decisions. The user needs to remain still; movement, lighting and camera settings can make estimates inaccurate.

Integration essentials
Check your build environment.
- Required skills
- C++ programming, OpenCV integration and basic understanding of neural networks.
- Browser build
- Emscripten compiles the engine to WebAssembly. Follow the included instructions and use the supplied OpenCV module.
- Other platforms
- Desktop, server, mobile and edge builds require the appropriate OpenCV dependency and build configuration. Porting and platform-specific optimization are your responsibility.
- Performance
- Depends on camera resolution, face count, models, hardware and browser. Evaluate representative conditions; the browser demo is not a benchmark for every device.
