MATLAB: Passing data between axes

axesdigital image processinggui

I am doing the GUI for image processing. I want to make about 2 axes in the GUI. I already manage to load image in axes 1. To continue, how can I pass the data of the image that I load on axes 1(that show original image) to axes 2(that show processed image) so that I can process the image in axes 2 without messing with the original image in axes 1?

  • You can:
    1) Create a dummy original image and store it in the handles structure of your GUI.
    handles.DummyImage = OriginalImage;
    2) In axes2, use something like:
    imshow(handles.DummyImage); % example to display the image
    %... do your processing.
    to retrieve it in your axes 2 and do whatever you want with it. Youcan store anything you want in the handles structure of the GUI, so it's easy to pass variables between multiple callbacks.
