Install the computer vision toolbox. If you don't have a license for it, then you cannot use the code you're trying to use.

I saw on mathworks that instead of using htextinsRED = vision.TextInserter('Text', 'Red : %2d', ... % Set text for number of blobs
'Location', [5 2], ...
'Color', [1 0 0], ... // red color
'Font', 'Courier New', ...
'FontSize', 14);
matlab now uses RGB = insertText(I,position,text)
the "I" is the image (grabbed one by one from the streaming webcam). how do I get the image if it is grabbed in the while loop below ?

It does not matter where your image comes from. As long as I is an image (i.e. a 2D matrix for greyscale images, a 3D matrix for colour images), insertText will work. As long as you have the computer vision toolbox installed and licensed of course.
