IJ_Isodata details

[iambeht]

Good day!

I research about the details and further explanation of the IJ_Isodata thresholding, but I did not found any resource aside from this http://imagej.nih.gov/ij/developer/source/ij/process/AutoThresholder.java.html. The content is just too short to describe the certain code.

I am using the said algorithm in my study, and I can't further explain the said algorithm because of its limited description.

With respect to the developers and authors, may I know more about the said algorithm? The details and mathematical formulation derived from the code or the study behind the algorithm.

Did you read the comments before the method code? There you can see
 
1) the Java code,
2) two separate explanations of the algorithm in plain English,
3) an example in pseudocode and
4) the reference to the original paper.

And here is a link to the paper (by googling the title).
http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=4310039

That should help to understand the algorithm.

Cheers

Thank you for the link. I've been searching this paper but I don't have the authority to access it.

In my study, I am using the Process/Binary/Make Binary which uses the function getAutoThreshold() method. And Sir Wayne answer my query that the getAutoThreshold() is similar to IJIsoData().

So what's the difference between the IsoData() and the IJIsoData() found in the http://imagej.nih.gov/ij/developer/source/ij/process/AutoThresholder.java.html?
