| Abstract: | Firstly,the theory of empirical mode decomposition(EMD) is introduced,and the reconstructing and filtering algorithm of intrinsic mode functions(IMF) from EMD is given in this paper.Secondly,some kinds of typical interfere signals are decomposed and filtered,abnormity picked-up by using of EMD technique in deformation data.By contrasting and analyzing,we think that the result is fairly effective.Lastly,it has shown that EMD may be a new effective processing method in analyzing of deformation observation. |
