ABSTRACT
The adoption of multiple macroblock partitions with variable block
sizes is one of the main reasons behind the superior coding effi-
ciency of H.264 video coding standard. Unfortunately, in motion
estimation phase, repeating Sum of Absolute Difference (SAD)
calculations for every possible block size incurs a heavy computa-
tional cost for the encoder. In this paper, in order to reduce the en-
coder complexity, we propose a hierarchical block matching based
