I've got this code that can detect a green object when it appears on the screen.

Here is the piece I am trying to alter

greenLower = (29, 86, 6)
greenUpper = (64, 255, 255)

Now I am trying to have the code to detect the white ball in the following images.

But I have been struggling with it.

This needs more detail to be answerable. – James Elderfield Aug 16 '16 at 15:41
white in HSV means to have saturation (2nd channel) close to zero, afaik. so try something like whiteLower = (0,0,minV); whiteUpper = (255,lowValue,255); For minV you have to choose something not too low to not get all the dark gray and black stuff, too. – Micka Aug 16 '16 at 15:51
