Deep dives on camera-based biometrics, SDK integration patterns, and building health-aware applications.
Step-by-step tutorial: capture webcam frames, send them to the rPPG API, and display live BPM. Working JavaScript code — from zero to heart rate monitor in under 80 lines.
Camera-based and wearable heart rate monitoring share the same physics but live in very different deployment realities. Accuracy comparison, failure modes, and a decision matrix for choosing the right approach for your application.
Your webcam can detect your heartbeat. Here's the rPPG pipeline from first principles — blood flow, light absorption, signal extraction, motion artifact rejection — and why wrapping it in an API is the right engineering call.
Remote photoplethysmography explained for developers. From face detection and ROI extraction to FFT-based heart rate calculation — plus a full SDK integration walkthrough and accuracy comparison against Binah.ai, NuraLogix, and Shen AI.
