Hi,

activecontour is from Image Processing Toolbox. Do you have it installed? What does

ver('images')

say and

license('test', 'image_toolbox')

Your way of getting a copy of the Mathworks activecontour routine is to upgrade your MATLAB to at least R2013a. If that is not an option for you, then look at the link I provided, which will take you to the File Exchange, where people have contributed a surprising number of different active contour routines. Look at the contributions there and pick out one that indicates it should work for your version. (If it indicates a later version then you still might be able to use it, but it might involve fixing some of the code.)
