Abstract
A method, apparatus, and manufacture for encoding a video sequence is provided. Encoding the video sequence includes performing a weighted prediction estimation between a reference frame of the video sequence and a target frame of the video sequence. Performing the weighted prediction includes performing an initial weighted prediction estimation for each block of the reference frame. Next, blocks are clustered according to their initial weighted prediction estimates. Then, each block of the target image is assigned to a corresponding region based on the clustering. During the video encoding, weighted-prediction is employed for each block according to its corresponding region.
