% Callback function for the "Load Image" button
function loadImageCallback(hObject, eventdata, handles)
% Open a file dialog to select an image
[fileName, filePath] = uigetfile({‘*.jpg;*.png;*.bmp;*.tif’, ‘All Image Files’; ‘*.*’, ‘All Files’}, ‘Select an Image’);
% Check if a file was selected
if isequal(fileName, 0)
return; % User canceled the operation
end
% Read the selected image
img = imread(fullfile(filePath, fileName));
% Check if the image was read successfully
if isempty(img)
errordlg(‘Failed to read the image’, ‘Error’);
return;
end
% Store the image data in the handles structure
handles.img = img;
% Update the handles structure
guidata(hObject, handles);
% Optionally, display a message to indicate successful loading
msgbox(‘Image loaded successfully’, ‘Success’);
