摘要
在分析了中值滤波的几种快速算法和硬件结构的基础上,提出了一种新的实现中值滤波的硬件方法,根据电视跟踪系统中图像的形成过程和系统对中值滤波的实时性和简便性的要求,将一维中值滤波或可分离中值滤波用于电视跟踪系统,并给出一个实时中值滤波器的小系统。
In this paper,four fast algorithms of median filter(MF)are analysed and a new hardware structure of MF is proposed.Based on the characteristic of video signal and the requirement of TV Tracking Systems,a 1☆3 1-D MF or the separated MF is most suitable for using in the TV Tracking System to filter out the noise signal from video signal.Also the circuits and results are discussed in detail in this paper.
