[Insight-users] OtsuThresholdImageFilter

[Uday Kurkure]

Hi John,

Here is a good explanation with an example:
http://www.labbookpages.co.uk/software/imgProc/otsuThreshold.html

<http://www.labbookpages.co.uk/software/imgProc/otsuThreshold.html>In
summary, OtsuFilter works for bimodal histogram (binary segmentation). It
searches exhaustively for a threshold value that gives minimum value for sum
of within-class variances. Alternatively, you can look for a threshold that
provides maximum value for between-class variance.

Its extension works for multi-modal histogram and provides multiple
thresholds, say N thresholds, for N+1 classes based on the same principle.
