how to make only image that i want, show on matlab?

i have a problem with my research about classification retinopathy diabetic using neural network, i have made a GUI to make user can easy to use. the problem is when i choose picture that non retina image, and i run the program to get exudate and bloodveseel, the system show the result in retinopathy grade with picture non retina image, how i can block that non retinal image can not be process on GUI.. thanks for answer

Just make sure you don't have any non-retina images in the folder or displayed in the listbox. Make sure you're using dir() only on the D:\TA\DR folder, and not on the D:\DR folder.

i am use this code to read one image on GUI

% --- Executes on button press in pushbutton1.

function pushbutton1_Callback(hObject, eventdata, handles)

% hObject handle to pushbutton1 (see GCBO)

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

proyek=guidata(gcbo);

[nama_file,nama_path] = uigetfile({'*.jpg';'*.bmp';'*.png';'*.tif'},'Buka Citra');

    if ~isequal(nama_file,0);

        handles.data1 = imread(fullfile(nama_path,nama_file));

        guidata(hObject,handles);

        axes(handles.axes1);

        imshow(handles.data1);

        title('Citra Asli');

    else

        return

    end

when my lecturer want to test the system using non retina image the result of classification is diabetic retinopathy grade.

Just take those images out of the folder. Otherwise you'll have to do some kind of check on each image, like it has a mean color close to some reference color.

ok sir, thx for helping

how i can make code on that GUI for only show image from path that i set, example D:\TA\DR\, the images on DR folder will be show on GUI and process but the image doesnt exits on DR folder will be not show.

I just don't know why it would be pulling images from some totally different folder that you didn't tell it about. Why would it do that?

extraction characteristics can not tell which is open retinal image or not, Because extraction of characteristic can not different retina or non retina image. if using images not retina and in the process when the system is getting results, and the results of feature extraction carried testing on neural network and get the result as the result in grade ur reasearch because of feature extraction from images not retina has similarities with retinal images of neural network that you are training
