Abstract

Two common techniques for compressing digital video are motion-compensated interframe coding and transform coding. In this paper, we combine the Lapped Orthogonal Transform (LOT) with motion compensated (MC) temporal prediction. The statistical structure of the MC frame differences is distinct from than that of still images. Therefore, we introduce a new lapped transform (the straddle LOT (SLOT)) which considers the structure of the MC frame differences. The combination of the conventional LOT with the SLOT, when applied to the entire image, forms the motion-compensated LOT (MCLOT). We demonstrate, both theoretically and on actual images, that the MCLOT outperforms the conventional LOT when applied to MC frame differences.
