realistic corpus of subjects performing physical activities on fitness machines | |
6 x 1 minute video recording (no sound) + ECG per subject (207 videos in total) | |
subjects: | 17 subjects (14 male, 3 female) with age range 20 to 53 years |
camera: | two RGB Logitech C920 webcameras - 30fps, 1920 x 1080 pixels stored in an uncompressed YUV planar pixel format (approx. 6GB per video) |
camera setup: | one Logitech camera was attached to the currently used fitness machine, the other was positioned on a tripod as close as possible to the first camera |
ECG: | two-lead Viatom CheckMe™ Pro device with CC5 lead |
activities: | speaking, rowing, exercising on a stationary bike and on an elliptical trainer; speaking and rowing performed twice - once with a halogen lighting resulting in a strong 50Hz (100Hz) temporal interference, once without |
lighting setup: | three lighting setups were used: (i) natural light coming from a nearby window, (ii) 400W halogen light and (iii) 30W led light |
measured HR: | the lowest 56 bpm, the highest 159 bpm, the mean 108.96 bpm, standard deviation 23.33 bpm |
i. The first frame of every video recording must not be used.
ii. The recordings of activity #4 for the subject #2 are missing for all cameras.
iii. The recordings of activity #2 for the subject #7 are missing for all cameras.
iv. Althought the videos are stored in a planar pixel format, 4:2:0 chroma subsampling was performed by the C920 webcameras before the signal was sent to the USB.
