- W2000320471 abstract "Abstract In this paper, we extend the idea of successive elimination algorithm (SEA) to obtain a fast full search (FS) algorithm accelerating the block matching procedure of motion estimation. Based on the monotonic relation between the accumulated absolution distortions (AAD) obtained for distinct layers of a pyramid structure, the proposed method successfully rejects many impossible candidates considered in the FS. The derivation of the monotonicity relation repeatedly uses in a four-dimensional vector space the l 1 -version of Minkowski’s inequality, an inequality which is quite well-known in the field of mathematics. Simulation results show that the processing speed is faster than that of several well-known fast full search methods, including the SEA that uses just once the Minkowski’s inequality (in a vector space of 256 dimension when the block size is 16×16). The processing speed of the proposed method is also competitive with that of the three-step search (TSS), which is often used for block matching in interframe video coding, although the visual quality performance of TSS is usually a little poorer than that of the FS." @default.
