Abstract
A method for selecting a picture prediction mode from a candidate pool of picture prediction modes for video compression takes advantage of similarity in implementation between SKIP and DIRECT modes and one other inter-picture prediction modes, namely, the 16×16 partition mode. The SKIP/DIRECT modes are considered if and only if the final prediction information of the 16×16 partition mode, including motion vector, reference picture index, and prediction direction, is the same as that of the respective SKIP and/or DIRECT modes. The same motion prediction, reference picture index and prediction direction are used for the 16×16 partition mode and the SKIP/DIRECT modes, and therefore, the same interpolation scheme can be used for both SKIP/DIRECT and 16×16 partition modes.
