Abstract
A new hardware-oriented algorithm called the one-dimensional full search (1DFS) is presented for block-matching motion estimation in video compression. The simulation for this algorithm follows H.261 and MPEG international standards. In MPEG simulation, structures with 1-, 2- and 3-frame interpolation are compared. The performance of 1DFS is superior to that of other fast search algorithms. And it has more regular data flow, data reuse and less control overhead. It is an alternative for 2D full search block matching and achieves a good compromise between computational complexity and performance. With competent performance and reasonable computation complexity, the proposed method is more suitable for real-time hardware realization of a VLSI motion estimator for video applications. >
