  Abstract

It is well known that a lot of computations are used for the motion estimation process in video coding. Recently, the MSEA was proposed to reduce the computation cost required for block matching in the motion estimation while keeping their accuracy. The MSEA evaluates lower bounds for the matching criteria for subdivided blocks in order to reduce the number of search positions. In this paper, we show that the lower bounds are calculated efficiently by using a lower bound that is already calculated for the first level. Based on this result, we propose a new fast full search motion estimation algorithm, in which the computation cost required for calculation of the lower bounds is reduced. The simulation results show that the proposed algorithm achieves computational saving as compared with the MSEA.
