[Insight-users] A question about bias field correction

[Luis Ibanez]

Hi Song,

Bias field correction is implemented in ITK
with the MRIBiasFieldCorrectionFilter

http://www.itk.org/Insight/Doxygen/html/classitk_1_1MRIBiasFieldCorrectionFilter.html

You will find a set of command line demo applications under

     InsightApplications/MRIBiasCorrection

Details about this demo application are available here

    http://www.itk.org/HTML/MRIBiasCorrection.htm



Before you jump into the code, you probably should read
the papers suggested in the Doxygen documentation of this
filter

"Parametric estimate of intensity inhomogeneities
applied to MRI" Martin Styner, G. Gerig, Christian
Brechbuehler, Gabor Szekely,
IEEE TRANSACTIONS ON MEDICAL IMAGING;
19(3), pp. 153-165, 2000,
(http://www.cs.unc.edu/~styner/docs/tmi00.pdf)


"Evaluation of 2D/3D bias correction with 1+1ES-optimization"
