How to divide live webcam video into MxN blocks so that input from each block can be read ?

I am displaying live video on the axes in GUI. What I want to do is to divide the video into 3x3 blocks so that I can read from each block.

Just like the person did in this video: https://www.youtube.com/watch?v=vSukMaQ4hbs

Simply use line() to draw lines over the live video. You will have to call "hold on" first.

then do color segmentation like I show you in my File Exchange and find the centroid of the colored item. Then see which of the "zones" or "boxes" it fits into. It's not a super challenging application. It should be pretty easy.
