Abstract
A method is provided. The method includes: determining one or more first candidate reference blocks that correspond to a current block in a first reference frame according to known motion information related to the current block; determining one or more second candidate reference blocks in a second reference frame; calculating a sum of differences between pixels of each of the one or more first candidate reference blocks and pixels of a second candidate reference block that is of the one or more second candidate reference blocks and that corresponds to the first candidate reference block; selecting a first candidate reference block and a second candidate reference block with a minimum sum of differences as a first reference block and a second reference block of the current block; and obtaining motion information of the current block according to motion information determined by the first reference block and the second reference block.
