Abstract

In this paper, an H.264/AVC video coding strategy is introduced that employs a spatial-temporal video sequence representation in which video frames are coded at a low spatial sampling rate and reference I frames are coded at high spatial resolution. High spatial frequency information is re-synthesized at the receiver side using an adaptive motion estimation and warping method. The approach as presented is shown to improve coding quality for sequences with low to moderate motion.
