摘要
在利用全方位多结构元形态滤波器的细节保持能力和改进的中心加权中值滤波的强去噪能力的基础上 ,结合最优全方位结构元约束层叠态滤波的思想 ,提出了一种混合滤波器设计方案 .理论分析和图像处理仿真实验表明 ,该滤波方案既能有效地滤除噪声 ,又可充分保留图像的细节。
By using the ability of better keeping the image's detail of the morphological filter with omnidirectional multiple structural elements and the ability of strong removal of noises of the improved center weighted median filter, a kind of designing project of the hybrid filter is suggested, which applied the idea of the stack filter based on omnidirectional structural elements. The theory analysis and the simulation experiment of the image processing indicated that this kind of filtering project can not only remove noises effectively but also keep the detail of the image sufficiently, especially the detail of high frequencey.
