Three algorithms for fast long-term memory block matching motion estimation are proposed. The algorithms are extensions of the fast single-reference simplex minimisation search (SMS) algorithm. The proposed algorithms represent different degrees of compromise between prediction quality and computational complexity. With a long-term memory of 50 frames the proposed algorithms have a computational complexity comparable to that of single-reference full-search while still maintaining the prediction gain of long-term memory motion estimation
