Otsu Threshold Segmentation
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 OtsuThresholdSegmentation/CMakeLists.txt will have to be tweaked to ensure tests pass.
Description
This filter creates a labeled image from a grayscale image. First, it calculates an optimal threshold that separates the image into foreground and background. This threshold separates those two classes so that their intra-class variance is minimal (see http://en.wikipedia.org/wiki/Otsu%27s_method). Then the filter runs a connected component algorithm to generate unique labels for each connected region of the foreground. Finally, the resulting image is relabeled to provide consecutive numbering.
