Subblock sum matching algorithm for block-based interframe coding

open access: yes, 1999
A fast block-matching algorithm for motion estimation is described for interframe image coding. Utilizing the fact that the motion is searched by a macroblock basis while the compression is performed by a block basis in many video compression standards ...
