I have an image and I need to hand pick some pixels for analysis. I want the image to come up zoomed in, then the user can graphically select some pixels for group 1, hit a keystroke (enter or space or something), then select the pixels for group 2. I would like the pixels to become greyed out or something similar when selected. I don't have the Image Processing toolbox and I can't afford it. I have been trying some things with the ginput function but I'm having a hard time. Any help? Thanks
