Abstract

An example system for monitoring heart rate can include: one or more processors; and storage media encoding instructions which, when executed by the processors, causes the system to: receive video data of a patient and a medical marker positioned on a skin of the patient, wherein the medical marker comprises a material configured to mimic optical properties of the skin; detect the skin of the patient within the video data to establish a monitoring region; detect the medical marker within the monitoring region; identify a region of interest on the skin within the monitoring region; generate a first photoplethysmography (PPG) signal from the region of interest and a second signal from the medical marker; minimize environmental noise from the first PPG signal using the second signal to form a modified signal; and generate a heart rate measurement based on the modified signal.
