how can I get the same values of IMFs of the reconstructed signal .

I found the IMFs of a signal / image by using Empirical Mode Decomposition and then reconstruct the signal by taking summation of all the ImF's. Now when I again check the imf's the values are different.... may be due to precision error of the processor.. Can i get the same values of imf's by using some methods.. Please help

How different are they? In absolute terms and in relative terms?

Here are few values of imfs which i got by applying emd program to a signal(imf) and the values of IMFs(imf1) i got from the reconstructed signal

*imf*=0  * _0.0168_*  -0.0150  -0.0205  -0.0046  0.0078  -0.0038        
      0  -0.0132 -0.0295  -0.0434  -0.0493 -0.0415  -0.0190     
      0  0.0073   0.0142   0.0203   0.0253  0.0288   0.0305    
imf1(from reconstructed signal)
0    0 * _.0170_*   -0.0151   -0.0210   -0.0051    0.0078   -0.0032        0   -0.0127   -0.0284   -0.0418   -0.0475   -0.0403   -0.0187           0    0.0036    0.0081    0.0130    0.0178    0.0221    0.0253

Did you use

http://www.mathworks.com/matlabcentral/fileexchange/21409-empirical-mode-decomposition

The program given at the above said link gives more error in my case. but i m using another program emd.m for finding imfs.this program is also available in matlabcentral.

the values in the reconstructed signal is different from the original values of IMFs... I want the same values of IMFs
