title: how to measure shift variance in discrete Wavelet transform (DWT) and complex wavelet transform
body: <p>I have a EEG data of epileptic patients. I have applied two different approaches for feature generation i.e Discrete Wavelet Transform (DWT) and Dual Tree Complex Wavelet Tranform(DTCWT). I have found better results with DTCWT. To support my approach , I want to show that DWT is shift variant but DTCWT do not get much affected by shift. 
  I have searched alot but could not find a proper way of comparing the shift variance of both dwt and dtcwt in python. Can someone help me?</p>
