Hi, for a project i am attempting to track coloured postcards against a white background. I have managed to get accurate tracking of red,blue and yellow but the green keeps escaping me. I have tried changing brightness,contrast and saturation, changing the level of RGB using jit.op but nothing works!

To track the other colours i mainly used the chromakey object with brcosa and jit.op, but this is where my method runs out of use. any one have any suggestions?
