Abstract
A method for block-based motion estimation, the flexible triangle search (FTS) algorithm is provided. The FTS is based on the simplex algorithm for optimization adapted to an integer grid. The proposed algorithm is highly flexible because of its ability to quickly change its search direction and to move toward the target of the search criterion. Motion estimation in a search window is in relation to a reference window. The motion estimation comprises searching. Searching is comprised of the steps of expanding, translating, contracting and reflecting. A system for block-based motion estimation is also provided.
