论文摘要
随着在线医疗的激增，需要对患者生命力进行远程监测。这可以通过从面部视频中计算生命体征的远程照相学（RPPG）技术来促进。它涉及处理视频帧以获取皮肤像素，从中提取心脏数据并应用信号处理过滤器以提取血量脉冲（BVP）信号。将不同的算法应用于BVP信号以估计各种生命体征。我们实施了一个Web应用框架，以测量一个人的心率（HR），心率变异性（HRV），氧饱和度（SPO2），呼吸率（RR），血压（BP）和面部视频的压力。 RPPG技术对照明和运动变化高度敏感。 Web应用程序指导用户减少由于这些变化而减少噪音，从而产生清洁剂的BVP信号。框架的准确性和鲁棒性在志愿者的帮助下得到了验证。
With a surge in online medical advising remote monitoring of patient vitals is required. This can be facilitated with the Remote Photoplethysmography (rPPG) techniques that compute vital signs from facial videos. It involves processing video frames to obtain skin pixels, extracting the cardiac data from it and applying signal processing filters to extract the Blood Volume Pulse (BVP) signal. Different algorithms are applied to the BVP signal to estimate the various vital signs. We implemented a web application framework to measure a person's Heart Rate (HR), Heart Rate Variability (HRV), Oxygen Saturation (SpO2), Respiration Rate (RR), Blood Pressure (BP), and stress from the face video. The rPPG technique is highly sensitive to illumination and motion variation. The web application guides the users to reduce the noise due to these variations and thereby yield a cleaner BVP signal. The accuracy and robustness of the framework was validated with the help of volunteers.
