I am working on whoodunit/pset4 and though I have removed the red noise and turned the reds to green and whites to yellow my image doesn't reveal any person or verdict so to speak, it moreof looks similar to my clue image not revealing anything then how do I proceed to resolve this? Any clues? Any suggestions will be appreciated!

  • Why not to put your code here? If you would do what you describe you should reveal the image (depends on what you mean by "removing red noise")

Well, this code does not do what you described. You assume that there are just two colors - pure red and pure white.

This is wrong assumption.

  • Hey! thanks for the advise, I just thought of that and now it's working as the clue image got not just pure red but many shades of red some with zero blue/green content and some with non-zero values.But it seems like the problem was just that simple to turn red to white and white to any shade of my choice.Took me almost a day!
