Side estimation plays an important role in Wyner-Ziv video coding. In this paper, we examine the use of two conventional motion search methods to improve side estimation. Unlike motion estimators used in conventional video encoders, side estimators do not have access to the original frame. This difference leads to some interesting observations concerning conventional motion search methods. Analytical and simulation results show that while multi-reference motion search is still effective, side estimators are not as sensitive to motion search pixel accuracies.
