  Abstract

An adaptive hexagon based search(AHBS) algorithm is proposed in this paper to perform block motion
estimation in video coding. The AHBS evaluates the value of a given objective function starting from a diamond-shaped checking block, and then continues its process using two hexagon-shaped checking blocks until the minimum value is found at the center of checking blocks. Also, the determination of which checking block is used depends on the position of minimum value occurred in previous searching step.
The AHBS is compared with other fast searching algorithms including full search(FS). Experimental results show that the proposed algorithm provides competitive performance with slightly reduced computational complexity.
