Access image information in multiply pushbuttons-Howto

Dear All,

I have a GUI pushbutton that allows me to choose an image (I) and shows it in Axes. I wish to use the same image (I) information for another operation using another pushbutton without the necessity to call it again but it can not access it. How can I do it.

Thanks.

This is a vague question yet. Without the necessity to call wahat again? And what cannot access what?

I guess, that you want to store the image data in the GUI figure:

img = imread(FileName);
axes;
image(img);

handles.image_data = img;
guidata(hObject, handles);

Now you can access the image data from each other callback:

function yourcallback(hObject, EventData, handles)
handles = guidata(hObject);
disp(handles.image_data);

But perhaps you want something completely different.
