论述了基于模糊规则的脉冲噪声滤波器。该滤波器由模糊脉冲噪声检测器、噪声消除器与模糊结合器构成。模糊脉冲噪声检测器用窗口内的中值与邻近像素信息来检测脉冲噪声，而脉冲消除器用最小最大值算法来计算噪声像素的估计值。与传统的脉冲噪声滤波器相比较，所设计的新滤波器具有良好的脉冲噪声抑制与图像细节边缘保护的性能。
An impulse noise filter based on fuzzy rules is discussed. The filter consists of a fuzzy impulse noise detector, a noise canceller and a fuzzy combiner. The fuzzy impulse noise detector detects the impulse noise using the median in the window and the neighboring pixel information, and the impulse canceller uses the minimum-maximum algorithm to calculate the estimated noise pixel. Compared with the traditional impulse noise filter, the new filter has good performance of impulse noise suppression and image detail edge protection.
