How does it work? Is it https://people.csail.mit.edu/mrub/evm/? I see the FAQ about VitalLens, but I couldn't find technical details.

It's super cool. Thanks for sharing. I want to build a biofeedback app for meditation and this looks like a good platform to use.

I found more details at https://www.rouast.com/blog/articles/vitallens-take-a-vital-... and https://arxiv.org/pdf/2312.06892.

It's still vague beyond saying they trained an AI: "VitalLens is trained on the PROSIT and Vital Videos Africa dataset...The time-synchronized sensor array used for PROSIT consists of a video camera, electrocardiogram (ECG), pulse oximetry, blood pressure monitor, and an ambient light sensor. "

What do you mean? Eulerian-Video-Magnification could be (and probably is) the underlying algorithm in the VitalLens API.
