Abstract
Motion-compensated video coding that employs fine-granular computational complexity scalable motion estimation is described. The scalable motion estimation technique adapts to varying computational limitations of the device performing the video coding technique. The scalable motion estimation technique calculates a predicted priority for each macroblock in a frame and identifies a set of macroblocks based on the predicted priority. A pass is then performed on each macroblock within the set. The pass checks a set of candidate motion vectors for each macroblock in the set and determines a new starting point for the next pass of the macroblocks during processing of the same frame. The predicted priority for each macroblock within the set of macroblocks is re-calculated and the process repeats by identifying another set of macroblocks and performing a pass on them. These repeats until a computation limit associated with the device performing the passes has been reached.
