de.unihalle.informatik.MiToBo.segmentation.thresholds.CalcGlobalThreshOtsu
@ALDAOperator(genericExecutionMode=ALL) public class CalcGlobalThreshOtsu
This class implements routines to calculate Otsu's threshold from given grayscale images.
Basically, a threshold is extracted that separates the image histogram in two classes, more or less equal in size and well-separated in terms of their average intensities.
Otsu thresholding is based on the following goal function,
