I'm creating a sort of image processing suite and each type of processing technique has its own GUI. So I want to activate a different image processing technique by clicking on a radio button. So I've created the gui that will do this for me and I've made it so that if a user selects "median filtering" then an action will be performed. My question is that since "median filtering" has its own GUI do I just access the median filter program by putting in openfig('medfilt.fig', 'new') in the appropriate section? Or should I be doing it another way?
