Adaptive numerical morphological filter for identifying chromatographic signals

A morphological algorithm has been proposed to filter away impulsive noises confounded in the chromatographic signal. Compared with the conventional m edian filtering method, the results showed that the proposed method has the advantages of a better filtering effect and less distortion. In particular , the morphological filter with adaptive scale gives very good results. (C) 1999 Elsevier Science B.V. All rights reserved.
