RESET Button in GUI

When I press the reset button, the original image doesn't appear, and there is no visible change (callback 5).

function varargout = GUITask1(varargin)
% GUITASK1 MATLAB code for GUITask1.fig
%      GUITASK1, by itself, creates a new GUITASK1 or raises the existing
%      singleton*.
%
%      H = GUITASK1 returns the handle to a new GUITASK1 or the handle to
%      the existing singleton*.
%
%      GUITASK1('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GUITASK1.M with the given input arguments.
%
%      GUITASK1('Property','Value',...) creates a new GUITASK1 or raises the
%      existing singleton*. Starting from the left, property value pairs are
%      applied to the GUI before GUITask1_OpeningFcn gets called. An
%      unrecognized property name or invalid value makes property application
%      stop. All inputs are passed to GUITask1_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
%      instance to run (singleton)".

It might be easier to help if you attached you mlapp file to your post using the paperclip icon, along with a couple sample images.

Which button is your reset button?

[Deema]

sorry, this when i upload image then RGB to Gray then i press reset

button number 5

What version of MATLAB are you using? Before you get too far into this project, I'd suggest switching to app designer. I think it will ultimately make things easier for you.

I'm assuming you want your reset button to show the original RGB image. However, each call to imshow clears the axes. When that happens, you lose your saved data, since you are saving it to the axes. You want to save it to your app instead.

In GUIDE, you do that by adding your variable to the handles structure, and updating it using guidata (see here)

% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
[baseFileName, folder] = uigetfile({'*.bmp;*.jpg;*.jpeg;*.png', 'Image Files (*.bmp,*.jpg,*.jpeg,*.png)'}, 'Select an image file');
if baseFileName == 0
    % User canceled the file selection
    return;
end
fullFileName = fullfile(folder, baseFileName);

% Store the original image in the UserData of axes3
handles.originalImage = imread(fullFileName);
imshow(handles.originalImage,'Parent',handles.axes3);

% Update handles structure
guidata(hObject, handles);

...

% --- Executes on button press in pushbutton5.
function pushbutton5_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton5 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
imshow(handles.originalImage, 'Parent',handles.axes3);

You'll want to make similar changes to all your callbacks.

In App Designer, you store it in an app property (see here)
