Profile

Hi HN, I'm Philipp, the solo founder of Rouast Labs.I've spent the last couple of years working on a new rPPG model, and I just published this blog post (which links to the full technical paper on arXiv) about the 2.0 version of my VitalLens API.The main breakthrough is that the new model is now accurate enough to robustly measure Heart Rate Variability (HRV) metrics (SDNN, RMSSD) from a webcam feed, not just heart rate.The blog post covers the new model architecture, the 1,400+ person training dataset, and performance benchmarks.I'm here to answer any questions about the model, the tech, or the challenges of building a bootstrapped API.Thanks for checking it out!

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

Its current recorded stage is Show HN launch.
