Blood Oxygen Saturation Estimation from Facial Video via DC and AC components of Spatio-temporal Map

no code implementations14 Dec 2022 Yusuke Akamatsu, Yoshifumi Onishi, Hitoshi Imaoka

Our method constructs CNN models that consider the direct current (DC) and alternating current (AC) components extracted from the RGB signals of facial videos, which are important in the principle of SpO2 estimation.

Adaptive Heart Rate Estimation from Face Videos

no code implementations18 Apr 2019 Utkarsh Sharma, Terumi Umematsu, Masanori Tsujikawa, Yoshifumi Onishi

We propose a novel heart rate (HR) estimation method from facial videos that dynamically adapts the HR pulse extraction algorithm to separately deal with noise from 'rigid' head motion and 'non-rigid' facial expression.
