Fingertip Videos for Heart Rate estimation

Videos of fingertip were recorded with Redmi Note 8 smartphone camera. Data was collected from 24 participants, both male and female in the age group of5 to 77 years. Each participant’s finger was illuminated withtorch light which was right next to the camera. The cameralens was then completely covered with the fingertip. Video was recorded for 20 seconds. The recording frequency of the camera was 30 frames per second (fps). Simultaneously, the ground truth HR was recorded using the Andesfit Health pulse oximeter. The dataset contained HR readings from 59 to 119 bpm. This dataset can be used to extract the PPG waveform from the videos. The ground truth heart rate recorded in excel file can be used as a reference to validate your estimations.本数据集的指尖影像由Redmi Note 8智能手机摄像头采集录制。数据来源于24名年龄介于5岁至77岁的男女参与者，每位参与者的手指由紧邻摄像头的手电筒灯光照明，随后将指尖完全覆盖摄像头镜头，录制时长为20秒，摄像头录制帧率为30帧每秒（fps）。与此同时，使用Andesfit Health指夹式脉搏血氧仪采集真实心率（ground truth HR）。数据集覆盖的心率读数范围为59至119次/分钟（bpm）。本数据集可用于从视频中提取光电容积描记（Photoplethysmography, PPG）波形，存储于Excel文件中的真实心率数据可作为验证心率估计结果的参考基准。
