摘要
建立了一种能自适应地调整尺度的形态滤波器对色谱信号中混杂的离散脉冲型噪声加以滤除的方法.结果表明,自适应形态滤波器在滤除脉冲型噪声时,比目前文献报道的中值滤波方法呈现出更好的效果,它能保存高度完整的信号信息,是处理色谱信号脉冲型噪声的有力工具.
A morphological filter has been constructed to filter the impulsive noises from chromatographic signal, in particular, morphological filter with adaptive scale give very good results in comparing with the convendonal median filtering method. The results show that the proposed method has advantages of better filtering effect and less distortion. This method is a powerful tool in processing chromatographic signal confounded with impulsive noise.
