This plugin was removed, as the Auto Threshold plugin from Gabriel Landini does a better job.


Multi_Thresholder.jar (30,729 Bytes)


in .jar file


This plugin allows the user to apply four different automatic thresholding algorithms. The four algorithms are ImageJ’s built in IsoData algorithm, Maximum Entropy Threshold, Otsu Thresholding, and Mixture Modeling. More information about thresholding and the algorithms employed here can be found at the Image Thresholding Tutorial.


This plugin is quite convenient, for it groups different techniques in one. It has nevertheless a major drawback when used on stacks. When operating on a stack, it computes the threshold on the single image currently displayed, and will apply this threshold value to all of the other images, which might not be relevant.
