Abstract

We present a novel, computationally efficient and robust scheme for multiple-initial-point predictors used in fast searches in the MPEG-2 standard. Extensive testing in a variety of video sequences with different motion characteristics clearly shows that it outperforms the center- and median-based predictors currently used by mean square error (MSE) reduction of 1.51, 5.25, and 3.62% for the diamond, the three-step, and the four-step searches and for the same bit rates as the standard.
