Higher Efficiency of Motion Estimation Methods
MetadataShow full item record
This paper presents a new motion estimation algorithm to improve the performance of the existing searching algorithms at a relative low computational cost. We try to amend the incorrect and/or inaccurate estimate of motion with higher precision by using adaptive weighted median filtering and its modifications. The median filter is well-known. A more general filter, called the Adaptively Weighted Median Filter (AWM), of which the median filter is a special case, is described. The submitted modifications conditionally use the AWM and full search algorithm (FSA). Simulation results show that the proposed technique can efficiently improve the motion estimation performance.
