環境光下の顔面皮膚動画からの血流脈波パルス抽出
額や頬骨の毛細血管を流れる血液パルスによる緑色スペクトル光吸収の微小変動を解析。
Illumination Invariant Chroma Decomposition
Projecting RGB pixel channels into chrominance subspaces eliminates false pulse signals caused by sunlight passing through highway roadside trees.
- Measures heart rate with ±1.5 bpm clinical accuracy without skin contact.
- Continuous pulse rate, respiratory rate, and blood oxygen estimation.
- Robust tracking across diverse skin tones adhering to the Fitzpatrick scale.
- Zero degradation under pitch-black night-time driving using 940nm infrared illumination.
