%Here there are a problem the code reads just the first image and give an error if i select any image from the same folder.

% --- Executes on button press in Browse.

function Browse_Callback(hObject, eventdata, handles)

% hObject    handle to Browse (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

      [filename, pathname] = uigetfile('*.tif', 'Pick an image');
      if isequal(filename,0) || isequal(pathname,0)
         disp('User pressed cancel')
      else
         a=imread(filename);
         axes(handles.axes1);
         imshow(a);

      end

Make it a full file name - folder plus base file name:

filename = fullfile(pathname, filename);

Start with my Image Segmentation Tutorial. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 It does all of the things you requested.

• read an image from a folder

variable_name=imread('image_name.ext')

• select image and show it into axes

imshow(variable_name)

• write into the image by making some filters

imwrite(Variable_consisting_processed_image,'output_filename')
