Dear Colleagues,
I have this strange behavior with the Non Local Means filter, used within the
macro below:
makeRectangle(1, 1, 835, 1025); run(“Crop”); run(“Duplicate...”, “title=Background”); run(“Mean...”, “radius=50”); imageCalculator(“Subtract create 32-bit”, “HAADF-08.jpg”,”Background”); selectWindow(“Result of HAADF-08.jpg”); rename(“Back_Corrected”); run(“8-bit”); run(“Duplicate...”, “title=BackCorrected_NLM”); run(“Non-local Means Denoising”, “sigma=15 smoothing_factor=1 auto”); run(“Duplicate...”, “title=BC_NLM_CLAHE”); run(“Enhance Local Contrast (CLAHE)“, “blocksize=257 histogram=256 maximum=3
mask=*None*”); run(“Set Scale...”, “distance=239 known=50 pixel=1 unit=nm”);
The filter crashes with “java.lang.ArrayIndexOutOfBoundsException” if I make a
rectangular selection and crop the image at the beginning.
The filter behaves normally if I don´t make a ROI.
It must be trivial but I just don´t get it. Any suggestions?
Thank you!
