Abstract
A method for motion estimation comprising the steps of (A) determining whether a cost of encoding one or more prediction parameters for a current search position is less than a current best cost, (B) when the cost of encoding the one or more prediction parameters for the current search position is greater than or equal to the current best cost, determining whether the current best cost is less than a minimum cost for encoding one or more prediction parameters of one or more remaining search positions and (C) ending the search when the current best cost is less than the minimum cost for encoding the one or more prediction parameters of the one or more remaining search positions.
