摘要

有效的运动估计是一个重要的问题，因为它决定了视频编码器的压缩效率和复杂度。运动估计可以表述为一个优化问题。本文首先介绍了基本的运动估计问题，讨论了视频运动估计的两种类型FSBME和VSBME估计的具体问题。本文分三个部分从三个方面概述了块匹配ME问题:1)降低计算复杂度;2)准确地表达真实运动;3)提高编码效率

Motion estimation method for video compression - an overview

Efficient motion estimation is an important problem because it determines the compression efficiency and complexity of a video encoder. Motion estimation can be formulated as an optimization problem. This paper starts with an introduction of basic motion estimation problem and discusses issues specific to video motion estimation of two types FSBME & VSBME estimations. This paper in three sections presents a overview of block matching ME problem in three directions: 1.) computation complexity reduction; 2.) accurate representation of true motion and 3.) improving coding efficiency
