Loading an image using a GUI in matlab

currently, i am involved in a project whose purpose is to extract characters from a water meter image just like its done in OCR. I am using matlab. I have created a GUI using Guide, and i would like to load an image of a water meter into it and then process it in such a way that i extract the characters and save them in a word readable and editable form. I have used the uigetfile function but all it does is to open the directory where the images are but to get the image into a work space within the gui is problematic, please help

When using GUIDE, the process for this is typically as follows.

1. In a callback, use uigetfile to grab file name and then load the data.

2. Add the data to the handles structure.

>> myData = imread('...')
>> handles.myData = myData;

3. Update the GUI's version of the handles structure using guidata.

>> guidata(hObject, handles)

4. Then, in subsequent callbacks, the data can be accessed in the handles structure:

>> image(handles.myData)

More info on guidata can be found here

There are other ways as well, but this approach is very common when using GUIDE. Hope this helps!
