Abstract

We present a new video mode for television sets that we refer to as display pixel caching (DPC). It fills empty borders with spatially and temporally consistent information while preserving the original video format. Unlike related video modes, such as stretching, zooming, and video retargeting, DPC does not scale or stretch individual frames. Instead, it merges the motion information from many subsequent frames to generate screen-filling panoramas in a consistent manner. In contrast to state-of-the-art video mosaicing, DPC achieves real-time rates for high-resolution video content while processing more complex motion patterns fully automatically. We compare DPC to related video modes in the context of a user evaluation.
