How to Get Min Threshold value from a Stack using Imagej?

[boina]

 I need to create a Jyton script to calculate a minimal threshold value from a stack of images. It doesn't have to be on one image at a time but the entire stack histogram at once.
Is there any method to get this threshold from a stack processor??
This is how I tried to do it:

        tempStackps = StackProcessor(tempStack)
        MinThresholdValue = tempStackps.getMinThreshold()

Thanks, jose.
