ImageRegistration

Group (Subgroup)

ImageProcessing (Misc)

Description

Uses itk's rigid translation image registration to calculate slice alignments using the specified image comparison metric and optimizer on the selected array. If apply shifts is selected subpixel shifts well be applied with linear interpolation. More information on comparison metrics and optimizers can be found in itk's documentation: http://www.itk.org/Doxygen/html/RegistrationPage.html
