Try one of my color segmentation demos in my File Exchange: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 Create a mask of the green pixels and then do something with it. You have not defined "remove" so I can't say exactly what you want. They can't be removed or deleted since the image must remain rectangular. But you can set the diseased part to another color if you want.

See where other people have worked on leaves with this link: http://www.mathworks.com/matlabcentral/answers/?term=tag%3A%22leaf%22

I did do some image analysis and gave code to someone here: http://www.mathworks.com/matlabcentral/answers/110329#answer_118985
