Yes, you either don't have the Image Processing Toolbox or a license for it:

Is it installed?

You probably don't have the Image Processing Toolbox. Try this:

% Check that user has the Image Processing Toolbox installed.
hasToolbox = license('test', 'image_toolbox');   % license('test','Statistics_toolbox'), license('test','Signal_toolbox')
if ~hasToolbox
  % User does not have the toolbox installed.
  message = sprintf('Sorry, but you do not seem to have the Image Processing Toolbox.\nDo you want to try to continue anyway?');
  reply = questdlg(message, 'Toolbox missing', 'Yes', 'No', 'Yes');
  if strcmpi(reply, 'No')
    % User said No, so exit.
    return;
  end
end
