I want to remove some parts(for example in 0-1 scale I want to remove 0.6 up to 0.9) in a RGB image. How can I do that?
I have a picture which background is white but there are noises there( the noises are like you have written something and cleared it with a rubber carelessly, so there are some shades or smth there remained), the written is with blue,black and red pens. I want to write a code that converts colors more than for example 0.8 to 1 so the background would be completely white.
Thanks in advance.
