Search for the tag leaf and you will find my code for doing exactly that for another person.

In general, you can go here to find demos for color segmentation and masking: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

Or else use the "Color Thresholder" app on the Apps tab of MATLAB.
