High-spatial-resolution videos offer the possibility of viewing an arbitrary region-of-interest (RoI) interactively. Zoom functionality enables watching high-resolution content even on displays of lower spatial resolution. If arbitrary regions corresponding to arbitrary zoom factors can be served to the user, the transmission and/or decoding of the entire high-spatial-resolution video can be avoided...
We consider a video transmission system that supports digital pan/tilt/zoom by cropping the region-of-interest (RoI) chosen by the user and encoding it before transmission. With a static camera, the motion in the transmitted video results mostly from changing the RoI. We propose an efficient technique for cropping the RoI in a way that yields low-energy residual after motion compensation performed...
