VARIABLE BLOCK SIZED HIERARCHICAL MOTION ESTIMATION

摘要

Systems, devices and methods are described for performing hierarchical motion estimation by downsampling a current frame to generate a downsampled current frame, specifying a downsampled block in the downsampled current frame, where the downsampled block corresponds to a block of the current frame, and specifying a source block associated with the downsampled block, where the source block is larger than the downsampled block. Motion estimation may then be performed in a downsampled reference frame using the source block.
