To display text on perticular location on image use function 'text'. Exa. to display text on location 100,100 use command text(100,100,'SomeTextHere') to display it on perticular location. If you want to display pixel dimension it requires a little trick. text(100,100,[ '[' num2str(x), num2str(y) ']']), this command will display content of x and y on image at location 100,100. This command can be used to display centroid of any tracked image over the image.

These will put stuff into the overlay. If you want text into the actual image itself, you'd need the computer vision toolbox which has an imtext() function. It just depends on what/where you mean by display.
