Blood Oxygen Saturation Estimation from Facial Video Via DC and AC Components of Spatio-Temporal Map

Yusuke Akamatsu, Yoshifumi Onishi, Hitoshi Imaoka

ICASSP 2023accepted

Peripheral blood oxygen saturation (SpO2), an indicator of oxygen levels in the blood, is one of the most important physiological parameters. Although SpO2 is usually measured using a pulse oximeter, non-contact SpO2 estimation methods from facial or hand videos have been attracting attention in rec…

Heart Rate and Oxygen Saturation Estimation from Facial Video with Multimodal Physiological Data Generation

Yusuke Akamatsu, Yoshifumi Onishi, Hitoshi Imaoka

ICASSP 2022accepted

Efforts to estimate multiple physiological parameters such as heart rate and oxygen saturation from facial videos have been made. However, training robust machine learning models for the estimation is challenging without large multimodal physiological datasets containing multiple physiological param…
