uulmMAD – uulm multiperspective action dataset. The uulmMAD dataset contains 14 actions in the area of everyday activities, fitness/sports and stretching performed by 31 subjects. Per subject, eight of the actions are repeated three times, six actions are performed four times with varying speed. Actions were recorded by three synchronized cameras (frontal, diagonal and lateral) with a frame rate of 30 Hz and an inertial motion capturing system with a sample rate of 120 Hz. Silhouettes were extracted using chromakeying. At the time we carried out the simulations, silhouettes were available for 22 subjects. In the first row exemplary pictures are shown for all actions. The number of videos (green) and total sum of frames (blue) which were available for the evaluation are displayed in the second row. At the bottom, an abbreviation for each action is defined and a short description is given. Written informed consent for the publication of exemplary images was obtained from the displayed subjects.
