摘要
中值滤波是实时图象处理中一种重要的去噪手段.本文对各中值滤波方案作了简要的回顾和比较,并提出了新的算法.文中给出了新算法硬件实现的原理框图并分析了它的特点.该功能板能在26.3ms时间内完成512×512×8bit图象的中值滤波.文章还提出了一些可供改进的意见.
Median filter is an important approach for removing moise in real time image processing. After brief review and comparing of different median filtering approaches, a new algorithm is suggested. Its principle diagram and characteristics of hardware are given. This modular board can fulfil median filtering of 512×512×8 bit image within 26.3 ms. Finally, we give some suggestions for improving hardware structure of median filter.
