MSPM: A Multi-Site Physiological Monitoring Dataset for Remote Pulse, Respiration, and Blood Pressure Estimation

TL;DR

The MSPM dataset provides a comprehensive resource for developing and evaluating camera-based remote vital signs estimation methods across multiple body sites, supporting research on pulse, respiration, and blood pressure.

Contribution

It introduces the first multi-site physiological monitoring dataset with ground-truth measurements for remote vital signs estimation, enabling advanced research in this area.

Findings

MSPM dataset is challenging but high quality, with intra-dataset pulse rate MAE below 4 BPM.

Cross-dataset pulse rate MAE can be below 2 BPM in some cases.

High correlation between remote and contact PTT suggests potential for camera-based blood pressure estimation.

Abstract

Visible-light cameras can capture subtle physiological biomarkers without physical contact with the subject. We present the Multi-Site Physiological Monitoring (MSPM) dataset, which is the first dataset collected to support the study of simultaneous camera-based vital signs estimation from multiple locations on the body. MSPM enables research on remote photoplethysmography (rPPG), respiration rate, and pulse transit time (PTT); it contains ground-truth measurements of pulse oximetry (at multiple body locations) and blood pressure using contacting sensors. We provide thorough experiments demonstrating the suitability of MSPM to support research on rPPG, respiration rate, and PTT. Cross-dataset rPPG experiments reveal that MSPM is a challenging yet high quality dataset, with intra-dataset pulse rate mean absolute error (MAE) below 4 beats per minute (BPM), and cross-dataset pulse rate MAE below 2 BPM in certain cases. Respiration experiments find a MAE of 1.09 breaths per minute by extracting motion features from the chest. PTT experiments find that across the pairs of different body sites, there is high correlation between remote PTT and contact-measured PTT, which facilitates the possibility for future camera-based PTT research.
