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 new adaptive morphological filter is proposed to filter out mixed impulsive noise in the chromatographic signal.The results show that the adaptive morphological filter is more effective in filtering impulsive noise than reported in the literature The median filtering method presents a better effect, it can save a high degree of integrity of the signal information, is a powerful tool to deal with the pulse noise of the chromatographic signal.
