Abstract
Methods and systems for using motion vector confidence to determine a FME patch priority list for a scalable coder are disclosed, and may include a fine motion estimator receiving a plurality of coarse motion vectors and corresponding confidences. A patch list may be generated based on the corresponding confidences of the coarse motion vectors. The patch list may then be used to determine a search area. Each video block in a present picture may be matched to the video blocks in the search area to find the best match. A fine motion vector may be determined for each video block in the present picture with respect to a video block in the search area.
