Hi  Samaneh,

I think  r>0.95 should mean that your signal is still intact. But you should have a look at  reference [1] as they have done something similar

[1] Iriarte, Jorge, et al. "Independent component analysis as a tool to eliminate artifacts in EEG: a quantitative study." Journal of clinical neurophysiology 20.4 (2003): 249-257.

Dear Bethel,
thanks a lot for your answer.
Now my question is is there any criteria for value of corr(EEG,EEG-EOG)?

Hi
One way: you could use correlation e.g obtain EOG free sections of the signal and compute correlation: corr(EEG,EEG-EOG).

Hi,
I would like to know how can I understand that EEG signal after reduction of EOG artifact using adaptive filter and wavelet transform consists same original information which it had before that.
