Hi, Usama
Here I give you sample code with GUIDE.
First, you need to create your GUI.
Type 'guide' in command window, and select 'blank GUI'
Then design your GUI. Your GUI must contains Axes, Pushbutton, and Edit as shown in the picture bellow
And type this code at 'pushbutton1_Callback'
function pushbutton1_Callback(hObject, eventdata, handles)
handles.output = hObject;
[fn pn] = uigetfile('*.dcm','select dicom file');
complete = strcat(pn,fn);
set(handles.edit1,'string',complete);
I = dicomread(complete);
imshow(I,[]);
guidata(hObject, handles);
I hope this clear.

Dear Usman,
If I understand you correct. You mean how to browse image from GUI right?
If yes then it is as follow:
a=imgetfile;
where a is your image.

complete = strcat(pn,fn);

Hi,
Here, I Just give you little hint.
Of course you cannot apply my code directly to your script.
You need to do your own modification.

Try MAGIC:
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.

Hi Chandra, I executed the above code & it's working for me. But could u plz tell me which line in ur code enables the image selected to be displayed in the axes. Actually I'm not able to understand the meaning of the line "handles.output = hObject; [fn pn] = uigetfile('*.dcm','select dicom file'); "
Regards, Seema

The "getfile()" line gets the filename (a string). imread() reads in the image from disk into a variable in your program. The "imshow()" line is the line that does the actual displaying of the image.

You posted this as an answer to Usama's question, but it's obviously not an answer to his question. So, if it's supposed to be a comment or followup question on one of the actual answers, whose answer are you commenting on? If you intended this to be a brand new discussion question of your own, then please post it as a new question, not as an answer.

i think you have misunderstood my question.
if true
% code
function pushbutton1_Callback(hObject, eventdata, handles)
handles.output = hObject;
[fn pn] = uigetfile('*.jpg','select jpg file');
complete = strcat(pn,fn);
set(handles.edit1,'string',complete);
I = imread(complete);
imshow(I,[]);
guidata(hObject, handles);
end
this is the code i used to browse the image when i click the pushbutton on the gui. now when i click the browse button i need to select an image from the drive, i need to display the image and i need to save the image to a variable so that i will be able to use it when i click the convert button.

I did answer the original questions about how to display (use imshow) and how to put the image into a variable (use imread). For your new question about how to access the image when you click a different push button, see the FAQ http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F

What must be the size of the axes to load the .jpg image? how can we relate the size of the image with the size of the axes ?

They're independent. Your image will scale to fit whatever size your axes is.
