01 / RESEARCH DETAILRemote pulse estimation and kiosk deployment

Challenge
Remote pulse models need physiological representations and an inference path suitable for embedded hardware.
Approach
Aligned global and local pulse spectra from the same video to learn shared physiological components without pulse labels.
Deployment
Co-developed models, converted inference to TensorRT FP16, integrated Jetson Nano and supported HEALLO field deployment.
