<div>Hi:</div>
<div>I'm using the MRIBiasFieldCorrectionFilter. </div>
<div>I input a smoothed image into the filter and set IsBiasFieldMultiplicative<br>as true, I get the bias corrected smoothed image.</div>
<div>Now I want to use the obained bias field to correct the original unsmoothed<br>image (image)</div>
<div>How to do that?</div>
<div>I iterately output the bias filed. After that I try to reconsturct the image as:</div>
<div>correctedImage = exp( log( image + 1 ) - bias ) - 1</div>
<div> </div>
<div>However, after I use the above formular to reconstructed the smoothedImage as </div>
<div> </div>
<div>correctedSmoothedImage = exp( log( smoothedimage + 1 ) - bias ) - 1</div>
<div>I find the result unmatch the image directly output by ITK. There're some pixels with different values.</div>
<div> </div>
<div>Thanks.</div>
