An improved algorithm of the optimal stack filter based on omnidirectional structural elements constrains 一种改进的最优全方位结构元约束层叠滤波设计方案
In order to remove noise in images perfectly, a class of the generalized morphological filters ( gmfs ) was introduced . we set up the relations between the gmfs and the stack filters, and analyzed the output statistical properties of the gmfs under various input distributions . by simulation and comparison, we verified that the gmfs had better performances than the traditional morphological filters in noise-suppressing and detail-preserving 为了更好地滤除图象中的噪声,本文研究了一种广义形态滤波器.在建立广义形态滤波器与层迭滤波器关系的基础上,分析了各种输入分布时,广义形态滤波器输出的统计特性.通过仿真比较,验证了在噪声抑制和细节保持方面,广义形态滤波器比传统形态滤波器有较好的性能
