Determining cardiac arrhythmia from a video of a subject being monitored for cardiac function

摘要: What is disclosed a system and method for processing time-series signal generated by video images captured of subject interest in non-contact, remote sensing environment such that the existence cardiac arrhythmia can be determined subject. In one embodiment, received. The was from region exposed skin where photoplethysmographic (PPG) signals registered. Signal separation performed on to extract Peak-to-peak pulse points are detected PPG using an adaptive threshold technique with successive thresholds being based variations previous magnitudes peaks. then analyzed obtain peak-to-peak dynamics. arrhythmias
