Little description:
I get an image from my scanner using Capture Core Framework and background color is gray. So I want to do white background.
I’m looking for best way to remove this color. I looked at Image Core Filters. And as I understood I should use those ones, but I couldn’t find included/ready filterfor this task. So, Do I have to write it myself?
It means to remove color I should write my own filter and apply it to my images? Right? Thank you.
UPD: I develop for Mac os
Why not just simply change the brightness of your image? If this gray background color value is fixed then you can increase the brightness a little bit, as a preprocess step, until you’re satisfied.
