Trying to use a live webcam feed to recognise either a red, green, or blue wooden block, however, I know due to lighting and other factors, the RGB values of these colours will fluctuate. I made a way of telling the difference between the blocks by saying if the red value in the RGB was higher than the green and blue values then output in a message box "red" and so on for the other colours.

My problem is that using the suckah object, you have to click on the object in order to get the RGB value. I have only seen other people track specific RGB values that do not fluctuate.

Is there a way of automatically clicking on the suckah object at a refresh rate? as this would solve the whole problem.

I've tried looking into matrixes etc. but it doesn't seem to do what I am trying to do.

I'm not precisely sure, what you want to do but you may be interested in [jit.findbounds] object which is designed to track defined color (with some "tolerance"). Check also cv.jit package (available via Package Manager) - if you need more features related to computer vision techniques.

In the narrower perspective: dig a bit into matrices, especially [jit.matrix] object and "getcell" message - useful, if you want to automatise operations on single pixels
