摘要
本文提出两种自适应窗非线性边缘保护滤波器。它们可同时滤除加性随机噪声、信号有关噪声和脉冲噪声,并有很好的边缘信号保护效果。其自适应窗的尺寸随信号的特征而变,以得到精确的信号估值,滤波器具有良好的滤波韧性和信号分辨力。
In this paper, two kinds of adaptive window nonlinear edge-preserving filters are proposed.They remove additive random noise, signaldepe-dent noise and impulsive noise simultaneously. Also, they preserve edge signalsquite well.The size of adaptive window is variated with the signal characteris-tics in order to obtain a precise estimate of the signal.The filters present goodftiltering robustness and signal resolution.
