In this paper, we have proposed a modified HBMA(Hierarchical Block Matching Algorithm) using the correlation of the motion vectors of the neighbour blocks in temporal and spatial directions. The initial translation of the first hierarchy is selected from its neighbouring blocks in spatial and temporal directions rather than to be set to zero.
Experimental results show that the computational cost to estimate the motion vector is reduce by 10% compared with Bierling's 2-hierarchical BMA and the correlation of the motion vector is slightly increased.
