【摘要】 空间域二维信号常代表图像信号,滤波是信号去噪最重要的方法。本文就空间域二维信号两种不同滤波方法——线性滤波和中值滤波进行了比较研究,将线性滤波与非线性滤波有机的结合,通过大量实验,得出应用混合型滤波的信号滤波方法。实验表明,混合型滤波器的滤波效果优于单型滤波器。更多还原

【Abstract】 2-D signal in the spatial domain means image signal, filtering is the most important method of signal remove noise. In this article there are two different methods that fittering-linear filtering and medium filtering , we compare two methods and combine them organically , through making a lot of experimentation , educing the mixed method of image remove noise. Experimentation shows that , mixed filtering is better than any of fitering.更多还原
