| 摘要: |
| 基于信号分解理论，在非线性秩排序统计滤波器基础上，提出一种新型的非线性滤波器结构——二值秩排序统计滤波器。主要工作包括:(1)提出了滤波器的定义和实现结构；(2)实现算法；(3)滤波特性分析；(4)噪声图象滤波的计算机仿真。理论分析和实验结果表明，本文提出的滤波器具有良好的脉冲干扰抑制能力和边缘保持特性，硬件实现简单。 |

| Abstract: |
| Based on the non-linear order sequencing filter and the theory of signal grouping, the author proposed the structure of a new kind of non-linear filter-double-value sequencing filter. The main work done includes:(1)proposed the definition and implementation structure of the filter; (2)implementation algorithm; (3)characteristic analysis of the filter; (4)computer simulation of noise image filtering. Theoretical analysis and experimental results show that the filter has a strong ability to restrain pulse interference and it has good edge-holding function. Its hardware implementatin is also easy. |
