In plain words: A free collection of face videos from 850 people, each paired with a heart-beat waveform and one blood pressure reading, shot in varied lighting and backgrounds. It lets researchers train cameras to read vital signs without contact, though skin colors are not evenly represented. Abstract · VitalVideos-Europe: A dataset of face videos with PPG and blood pressure ground truthsWe collected a large dataset consisting of 850 unique participants. For every participant we recorded two 30 second uncompressed videos, synchronized PPG waveforms and a single blood pressure measurement. Gender, age and skin color were also registered for every participant. The dataset includes roughly equal numbers of males and females, as well as participants of all ages. While the skin color distribution could have been more balanced, the dataset contains individuals from every skin color. The data was collected in a diverse set of locations to ensure a wide variety of backgrounds and lighting conditions. In an effort to assist in the research and development of remote vital sign measurement we are now opening up access to this dataset. vitalvideos.org for all datasets. | |

When this technology matures, it will transform smartphone cameras into health monitoring devices.
The dataset is for academic research (free) and companies to create models on top of it. If enthusiastic non-academics would like to use the dataset then this is certainly a possibility. Just explain your intent and promise not to share the dataset itself. You are very much encouraged to publish the results of your work (code, models, ...) publicly.
You can request access through the email in my profile. I am not allowed to publish (part of) the dataset publicly without monitoring access to it because it contains identifiable individuals. If you'd like to download one sample: https://www.dropbox.com/sh/pchhxratjij4td8/AACeHfN2qwZn4cSrD...

I started this project on my own a year ago when I got very interested in the area and my next projects are collecting a very large dataset in Sub Saharan Africa and also a dataset consisting of low SpO2 values.
If you also have an interest in the area, introduce yourself to me through [email protected]!
