A speculative start point selection for motion estimation iterative search improves the efficiency and quality of the integer-pel motion estimation iterative search by speculatively selecting the start position of the iteration. The start position is selected by comparing the Sum of Absolute Differences (SAD) value of a 0 motion vector, a predicted motion vector and a global motion vector (GMV) and selecting the position with the smallest SAD value. A refinement scheme with a threshold improves the efficiency and quality of the motion estimation iterative search by performing several comparisons to ensure the proper motion vector is selected. Applications of this improved motion estimation search include stabilizing an image as well as many other applications where motion vectors are used.
