Determines a threshold according to a given method and saves it to the threshold_value variable.
The automatic thresholder utilizes the threshold methods from ImageJ on a histogram determined on the GPU to determine a threshold value as similar as possible to ImageJ ‘Apply Threshold’ method.
Enter one of these methods in the method text field: [Default, Huang, Intermodes, IsoData, IJ_IsoData, Li, MaxEntropy, Mean, MinError, Minimum, Moments, Otsu, Percentile, RenyiEntropy, Shanbhag, Triangle, Yen]
Availability: Available in Fiji by activating the update sites clij and clij2. This function is part of clij2_-188.8.131.52.jar.
Ext.CLIJ2_getAutomaticThreshold(Image input, String method, Number threshold_value);
The code for the automatic thresholding methods originates from https://github.com/imagej/imagej1/blob/master/ij/process/AutoThresholder.java
Detailed documentation on the implemented methods can be found online: https://imagej.net/Auto_Threshold
