This module is NOT actively supported or maintained (See #3401). The associated code has been copied from Slicer r23589

Note that the code is expected to compile against Slicer 4.4. That said, the OtsuThresholdImageFilter/CMakeLists.txt will have to be tweaked to ensure tests pass.

This filter creates a binary thresholded image that separates an image into foreground and background components. The filter calculates the optimum threshold separating those two classes so that their combined spread (intra-class variance) is minimal (see http:https://en.wikipedia.org/wiki/Otsu%27s_method). Then the filter applies that threshold to the input image using the itkBinaryThresholdImageFilter. The numberOfHistogram bins can be set for the Otsu Calculator. The insideValue and outsideValue can be set for the BinaryThresholdImageFilter. The filter produces a labeled volume.\n\nThe original reference is: \n\nN.Otsu, "A threshold selection method from gray level histograms," IEEE Trans.Syst.ManCybern.SMC-9,62-66 1979.
