ABSTRACT:
More efficient global motion compensation is provided by merging the warping processes performed in various global motion compensation (GMC) functions into a single warping process for use in GMC encoding and decoding operations. In an encoder in accordance with the invention, a global motion estimation processor is provided for performing global motion estimation (GME) on a picture. A mode decision processor is provided for selecting macroblocks (MBs) of the picture for GMC coding. A warping processor is provided for performing a single warping process for each pixel in the selected MBs for use in a plurality of GMC operations other than GME. A global motion compensation processor is provided for performing the GMC operations. Variable length encoding and texture coding is provided for encoding the picture to produce a GMC encoded bit stream.
