Abstract

Current implementations of MPEG2 encoders are specially designed in order to perform a huge number of operations, most of which occur during motion estimation. Many fast algorithms have been proposed to reduce the processing power necessary. This paper examines the results achieved by several methods that show promise for reducing computation while sacrificing as little image quality as possible. Methods that achieve these goals are desirable for use in future encoders that will be implemented on generic digital signal processors (DSPs).

数字信号处理器运动估计算法的性能评价

目前MPEG2编码器的实现是为了执行大量的操作而专门设计的，其中大部分操作发生在运动估计期间。人们提出了许多快速算法来降低所需的处理能力。本文考察了几种方法所取得的结果，这些方法显示了在尽可能少地牺牲图像质量的同时减少计算量的希望。实现这些目标的方法对于未来将在通用数字信号处理器(dsp)上实现的编码器使用是可取的。
