  1. Call uigetfile() to get the input filename.
  2. Call imread() to read the input image from the disk into a variable in memory.
  3. Process the image in whatever way you want.
  4. Call imshow() to display the image in the axes.
  5. Call uiputfile() to get an output filename.
  6. Call imwrite() to save the image to disk.
If your image has annotation in the overlay (arrows, text, etc.) then use export_fig() - see the File Exchange. It's the first one you see on the File Exchange screen because it's the most downloaded function of all.

Image Analyst's answer is great. I would only add that if the image in your GUIDE GUI has been somehow modified from the version originally read from the file, or if the 'cdata' of your image is stored in the .fig file of your GUI and you don't have access to the original file that the image came from, you would use the following modification to Image Analyst's steps:
  1. Execute "hIm = findall(hAx,'type','image')", you'll need to change hAx to the actual variable name of your axes handle.
  2. Execute get(hIm,'CData') to read the image data in axes1 into a variable in memory
  3. Process the image in whatever way you want.
  4. Call imshow() to display the image in the axes.
  5. Call uiputfile() to get an output filename.
  6. Call imwrite() to save the image to disk.
