Key result
CLBP-400 dataset provides paired facial rPPG video and hemodynamic data across ~400 adults.
Why the study?
The development of remote blood pressure measurement algorithms using remote photoplethysmography has been limited by the small size of publicly available datasets, privacy concerns regarding facial videos, and a lack of diverse, realistic datasets associated with actual blood pressure measurements.
Observational (n=400)
This study provides the CLBP-400 dataset of 400 adult facial videos paired with clinical blood pressure and heart rate measurements to aid the development of cuff-less blood pressure estimation algorithms.
Enables privacy-preserving rPPG-BP dataset development; leaves open prospective clinical validation before algorithm adoption.
The development of remote blood pressure (BP) measurement algorithms using remote photoplethysmography (rPPG) has significant limitations, including the small size of publicly available datasets, privacy concerns regarding facial videos, and a lack of diverse, realistic datasets associated with actual BP measurements. To address these challenges, this study aimed to provide comprehensive, simultaneous recordings of participants’ faces, along with reference physiological measurements, for 400 adult participants aged 18–79 years. For each imaging session, systolic and diastolic blood pressure and reference heart rate (HR) were recorded using clinical electronic BP monitors in addition to recording illuminance (lux) values for indoor and outdoor environments. The collected data, called CLBP-400, is a crucial resource for developing and evaluating remote vital signs from facial rPPG signals. A sample of videos is publicly available to demonstrate data quality, while academic researchers can access the complete dataset under a strict data use agreement.

Al-Naji et al. (2026) conducted an observational in Blood pressure estimation (n=400). Remote photoplethysmography (rPPG) facial video recording vs. Clinical electronic blood pressure monitors was evaluated on Simultaneous facial video recordings with reference systolic and diastolic blood pressure, heart rate, and illuminance measurements. The CLBP-400 dataset provides simultaneous facial rPPG videos and reference blood pressure and heart rate measurements from 400 adults aged 18-79 years.
