Very cool. Are you guys doing statistical filtering at all or is it strictly palette matching? Seems like your data inputs are specific enough that you are trying to get where you don't need much buffer on either side of the wavelength.
I can also imagine MLB having similar concerns as the NFL when, for instance, they insisted on removing the line as the ball is being spotted. That is, if they are showing the strike zone and the ump's call seems inconsistent, then it wouldn't be a "good look" for the sport.
