Abstract: A motion estimation method is provided which includes for each respective block of the current frame, selecting a candidate set associated with the current frame and a previous frame, the candidate set comprising at least one spatial candidate block in the current frame and a plurality of temporal candidate blocks in the previous frame, wherein the step of selecting the candidate set comprises: selecting the at least one spatial candidate block directly adjacent to the each respective block from the current frame; and selecting the plurality of temporal candidate blocks directly adjacent to a reference block from the previous frame; and determining a motion vector according to the candidate set for the each respective block of the current frame.
