摘要
In at least one embodiment, a motion estimation method may include dividing a first video frame to be estimated into a plurality of macroblocks, in which each of the macroblocks includes a plurality of sub-blocks. The method may further include determining a sampling pattern for each sub-block based on visual data of the sub-block, and determining a prediction motion vector for each sub-block by performing a pre-search based on the sampling pattern of the sub-block. The method may further include determining a search template for each macroblock based on the prediction motion vector of each sub-block within the macroblock, and determining a prediction motion vector for each macroblock by performing a secondary search based on the search template of the macroblock.
