I stored an image data using setappdata in this function. I would like to use this image data twice in 2 separate functions. How can this be done?

Either use nested functions and shared variables, or getappdata() in both functions where you need the data.

getappdata() does not display data; you need to imshow() or image() or imagesc() the retrieved data.
And of course the retrieval has to be after the data has been stored; in your second case your flow of routines might not have stored it yet.
