MATLAB: How to use regionprops in matlab

image processingImage Processing Toolboxintensitymeanmissing toolbox

I have writen a code like this to calculate the mean intensity of my masked image, but it keeps having errors saying that 'regionprops' require Image Process Toolbox.
May I ask what went wrong with this code?

Best Answer

Try this:
% Check that user has the specified Toolbox installed and licensed.
hasLicenseForToolbox = license('test', 'image_toolbox');	% Check for Image Processing Toolbox.
% hasLicenseForToolbox = license('test','Statistics_toolbox');	% Check for Statistics and Machine Learning Toolbox.
% hasLicenseForToolbox = license('test','Signal_toolbox');	% Check for Signal Processing Toolbox.
% hasLicenseForToolbox = license('test', 'video_and_image_blockset');	% Check for Computer Vision System Toolbox.
if ~hasLicenseForToolbox
	% User does not have the toolbox installed, or if it is, there is no available license for it.
	% For example, there is a pool of 10 licenses and all 10 have been checked out by other people already.
	ver % List what toolboxes the user has licenses available for.
	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
