摘要
提出双窗自适应加权中值-截尾均值滤波算法。根据信号结构特征设计出自适应计算滤波参数的方法,该方法在抑制加性混合噪声和保图像细节等方面有优良的性能,综合性能优于3LH+、DWMTMF、ACWM。
Double Windows Adaptive Weighted Median-Trimming Mean Filter Algorithm is derived in the paper. This filter has good performance in preserving image details while suppressing additive white and/or impulsive-type noise, because the adaptive scheme to compute filtering parameters based on the signal structure is designed. Its synthetic performance is better than 3LH+、DWMTMF、 ACWMt、also.
