Abstract

Based on a recent study on the optimal FIR stack hybrid (FSH) filtering under the mean absolute error criterion, weighted FIR median hybrid (WFMH) filters are proposed in this paper. These filters do not need any complicated design procedure, as do the optimal FSH filters, but include many FSH filters commonly used in practice. Some properties of WFMH filters are studied and the applications of WFMH filters to image recovery from impulsive or Gaussian noise are considered.<>

加权FIR中值混合滤波器用于图像处理
基于平均绝对误差准则下最优FIR叠置混合滤波器的研究,提出了加权FIR中值混合滤波器。这些滤波器不需要任何复杂的设计程序,如最优的FSH滤波器,但包括许多在实践中常用的FSH滤波器。研究了WFMH滤波器的一些特性,并考虑了WFMH滤波器在脉冲噪声和高斯噪声下图像恢复中的应用。
