Abstract
(EN)
A pulse wave detection method and device, and an electronic device, the method comprising: acquiring grayscale change curves of three colors from a video of a region of interest; decomposing the grayscale change curve into one or more independent components by means of independent component analysis; and determining a pulse wave from the one or more independent components according to the amplitude or periodicity of the one or more independent components.
(FR)
L'invention concerne un procédé et un dispositif de détection d'onde pulsatile et un dispositif électronique, le procédé consistant à : acquérir des courbes de changement d'échelle de gris de trois couleurs à partir d'une vidéo d'une région d'intérêt ; décomposer la courbe de changement d'échelle de gris en une ou plusieurs composantes indépendantes au moyen d'une analyse de composantes indépendantes ; et déterminer une onde pulsatile à partir de ladite une ou desdites plusieurs composantes indépendantes en fonction de l'amplitude ou de la périodicité de ladite une ou desdites plusieurs composantes indépendantes.
(ZH)
一种检测脉搏波的方法、装置和电子设备,该方法包括:从感兴趣区域的视频中获取三种颜色的灰度变化曲线;通过独立成分分析将灰度变化曲线分解为一个或多个独立成分;根据一个或多个独立成分的幅值或周期性,从一个或多个独立成分确定所述脉搏波。
