Dear mailing list members,
Is the result of OtsuThresholdImageFilter equivalent to the result of
OtsuMultipleThresholdsImageFilter with NumberOfThresholds = 1?
I'm wondering why the ITK OtsuThresholdImageFilter yield different
Otsu-threshold values than another program called MAVI. The found values
differ significantly between ITK and MAVI.
Why could that be?
MAVI doesn't bin the histogram, so for 8-bit input I use 256 as
NumberOfHistogramBins in ITK. Would that be correct?
Any help is very much appreciated
Roman
