CLBP-400: A Real-World Video Dataset for Cuff-Less Blood Pressure Estimation via rPPG

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.

Access to Full Dataset: The full CLBP-400 dataset (400 high-quality videos and physiological metadata) is not hosted directly on Zenodo to ensure participant privacy and data integrity.
