Computer vision for non-contact blood pressure (BP): preliminary results

open access: yes, 2023
Traditional contact blood pressure (BP) measurement is restrictive and uncomfortable for the patients. Remote sensing with imaging photoplethysmography (iPPG), in contrast, allows for easy, nonrestrictive, contactless and cost- effective extracting of ...
