How to separate black colors exactly in qr code image(color segmentation)

hi , i have a problem about separating black colours from white colours on qr code image since qr code is shaded image as you see on the figure below. First i use deconstruct mesh command then i use color infos from meshes.As you see i can only separate some portion of black colours but i cannot select shaded parts on the image. To separate black and white i use Split ARGB command but result is like that. So how can i achieve this ? Thanks in advance for your answers :slight_smile:
