How do I allow user to choose either a folder or an image(or selective images) to run the rest of the functions?

Currently it is able to select a folder but I want the users to have other options if they want to select an image/ selective images instead.

%% ACCESS ALL IMAGES IN THE FOLDER
selpath = uigetdir;
imageFolder = dir(fullfile(selpath,'\*.jpg'));
numfiles = length(imageFolder);
ori_roi = cell(numfiles, 1);
i = 1;
%% LOOP THROUGH ALL IMAGES IN THE FOLDER & RUN ALL THE 5 FUNCTIONS
for i=1:length(imageFolder)
    tic
        functionError = 0;
        
        filename = fullfile(selpath,imageFolder(i).name);
        originalImage = imread(filename);
        
        fprintf("Image name: %s\n",imageFolder(i).name);
        ...

Thanks for the reply but it doesn't work for my case. Unable to see the individual images when i clicked on the folder.

Shu - please clarify what you mean by unable to see the individual images. Where are you expecting to see them? Are you not seeing the files or are you expecting to see the actual image?

在 MATLAB Online 中打开

choice = menu('How do you want to select images?', 'by folder', 'individual image');
switch choice
    case 0
        %user cancelled
        return
    case 1
        %% ACCESS ALL IMAGES IN THE FOLDER
        selpath = uigetdir;
        if ~ischar(selpath)
            %user cancelled
            return
        end
        imageFolder = dir(fullfile(selpath,'*.jpg'));
        filenames = fullfile(selpath, {imageFolder.name});
    case 2
        %% ACCESS ONE IMAGE IN A FOLDER
        [selfile, selpath] = uigetfile({'*.jpg', '*.png', '*.tif', '*.*'}, 'Pick a file');
        if ~ischar(selfile)
            %user cancelled
            return
        end
        filenames = {fullfile(selpath, selfile)};
    otherwise
        error('somehow choice is out of range??')
end
numfiles = length(filenames);
ori_roi = cell(numfiles, 1);
%% LOOP THROUGH ALL IMAGES IN THE FOLDER & RUN ALL THE 5 FUNCTIONS
for i=1:numfiles
    tic
    functionError = 0;
    
    filename = filenames{i};
    [~, basename, ~] = filepaths(filename);
    originalImage = imread(filename);
    
    fprintf("Image name: %s\n",basename);
    ...
    ori_roi{i} = ....
    toc
end
