This paper presents a new motion estimation algorithm to improve theperformance of the existing searching algorithms at a relative lowcomputational cost. We try to amend the incorrect and/or inaccurateestimate of motion with higher precision by using adaptive weightedmedian filtering and its modifications. The median filter iswell-known. A more general filter, called the Adaptively WeightedMedian Filter (AWM), of which the median filter is a special case, isdescribed. The submitted modifications conditionally use the AWM andfull search algorithm (FSA). Simulation results show that the proposedtechnique can efficiently improve the motion estimation performance.
