      Serrano, Ana; Garces, Elena; Masia, Belen; Gutierrez, Diego (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Video capture is limited by the trade‐off between spatial and temporal resolution: when capturing videos of high temporal resolution, the spatial resolution decreases due to bandwidth limitations in the capture system. ...
