i want to make a step sequencer with lego (16×16) bricks filmed with my web cam.

i know how to track ONE brick in different colours and get the position coordinates but i don’t know how to track more bricks at the same time and how i can save the information in a matrix.

please help me

You get a black background with the chosen color block in white. Then do blob tracking using cv.jit: http://jmpelletier.com/cvjit/ Duplicate for each of your colors.

Maybe cv.jit can even do your color tracking for you. It’s been a while since I used it.
