Did you mean RGB to Grayscale? How about using basic Simulink blocks to implement the equation here: <http://www.mathworks.com/support/solutions/en/data/1-1ASCU/index.html?product=IP&solution=1-1ASCU>

If you try want binary, perhaps you can then just set a threshold of 0.5 and round off the intensity values to a 0 or 1
