Abstract
A method for processing a plurality of motion vectors is disclosed. The method includes determining a number of different block sizes in the video frame; and, performing a variable block size motion vector process if the number of different block sizes in the video frame is greater than one, the variable block size motion vector process comprising constructing a pyramid of motion vectors from the plurality of motion vectors, the pyramid having at least a first layer and a second layer of motion vectors, each of the first and second layers having a set of motion vectors based on a particular block size. An apparatus for performing the inventive method is also disclosed.
