Hello Herbie,

thanks for your answer! It turned out that a simple call to  IJ.run(img, "Auto Threshold", "method=Shanbhag white");  did the trick.
I'm pretty new to ImageJ and didn't know it had such a nice function.

Thanks a lot!

Good day Gebhard,

did you try recording the processing steps using the Java-recorder?
(Plugins > Macro > Record > Java)
