Abstract

This paper presents a fast full-search algorithm (FSA) for rate-constrained motion estimation. The proposed algorithm, which is based on the block sum pyramid frame structure, successively eliminates unnecessary search positions according to rate-constrained criterion. This algorithm provides the identical estimation performance to a conventional FSA having rate constraint, while achieving considerable reduction in computation.

摘要

本文提出了一种用于速率受限运动估计的快速全搜索算法（FSA）。该算法基于块和金字塔帧结构，根据速率受限准则依次消除不必要的搜索位置。该算法在实现显著计算量减少的同时，提供了与具有速率约束的传统FSA相同的估计性能。
