'Spot the ball' was a staple of local newspaper competitions - an action shot of a game with the ball removed by presumably pre-digital photographic trickery. Entrants were invited to mark a cross where they thought the ball might have been, and the closest to the original centre co-ordinates won a prize.
So yeah, surprisingly tricky, but you could set up a big training set along similar lines.
- sosuke 6y agoI've seen that online with big costs for guesses and prizes. Many years ago but I'm sure it is still around. I thought about how to computationally determine the ball position until I read that the ball position was decided by an impartial referee's opinion.
- revbingo 6y agoActually not the original co-ordinates, but a point arbitrarily decided by a panel. I suspect that's where most people went wrong! https://www.theguardian.com/football/shortcuts/2015/jan/14/how-to-spot-the-ball-in-spot-the-ball https://www.theguardian.com/football/shortcuts/2015/jan/14/h...
