Hey, Im trying to build a GUI for the Quality Assessment tools of an X-Ray machine. In this , i have to load an image and then do various operations on it. I have created a push button to load my image and another push button to do operations on it. I have to send the image from the callback of the Load Push Button to the callback of the push button of the Operations. Please help me how to do this! Thanks a lot.

Hi,
In callback of Load Push Button you should write like this :
handles.output = hObject;
[fn pn] = uigetfile('*.jpg','select image');
if fn ~= 0
handles.I = imread(fullfile(pn,fn));
imshow(handles.I);
end
guidata(hObject, handles);
In the other pushbutton, I will threshold the image.
And then in the other push button you can call the image by :
handles.output = hObject;
handles.bw = im2bw(handles.I);
imshow(handles.bw);
guidata(hObject, handles);

Try this image processing GUI framework. It will get you up to speed quickly:
Description
This GUI will help the novice user get up to speed very quickly on using GUI-based applications. Everything is laid out in a very simple Step 1, Step 2, Step 3, etc. layout. It is a very good starting point for a typical image analysis application. This application uses GUIDE to do the user interface design, and has most of the basic controls such as buttons, listboxes, checkboxes, radio buttons, scrollbars, etc. It allows the user to select a folder of images, select one or more images and display them, to select a series of options, and to individually or batch process one or more images. The user can optionally apply a mask (region of interest) to the image so that only the area within the mask will be analyzed. The results are optionally sent to Excel. In this demo, I do some very basic particle sizing but in use, the user would replace that simple demo code in the function AnalyzeSingleImage() with their own code. Works with Windows or Unix since paths are all forward slashes. Requires the Image Processing Toolbox to do the simple particle sizing demo, but if you delete that demo code before using it, then the IP toolbox would not be required and it would still demonstrate the basic GUI-based file processing functionality.

You can use uigetfile with 'multiselect' -> 'on'
And when reading the image, you can use for loop
Eq:
handles.output = hObject;
[fn pn] = uigetfile('*.jpg','select image','multiselect','on')
if ~isempty(fn)
for x = 1 length(fn)
handles.I{x} = imread(fullfile(pn,fn{x}));
end
end
guidata(hObject, handles);
In another pushbutton callback, you can call the image by the index
Eq:
handles.output = hObject;
handles.bw = im2bw(handles.I{1});
imshow(handles.bw);
guidata(hObject, handles);

What is 'data_Callback'?
Your function?
Can you show me about 'data_Callback'?
