Today my iPhone suggested that I look at an automated album of home cooked food from my photos. It was working pretty well as I scrolled through and then it came up with some poop on the ground that for some reason I had taken a photo of. Kind of disconcerting.

I mean it _was_ food.

Either train more with bald players, or do better at choosing the 'thing that is being converged upon'. Humans would be able to follow a game regardless of the shape or color of the ball's appearance.

I imagine for soccer the task of determining where the ball is based on player locations would be a lot harder than you think.

'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.

I can't say I'm super surprised that their training data didn't include pictures of poop, as I imagine (or do I just hope?) that most people don't take many pictures of that.

Mmmm. Bowl of chocolate ice cream, tasty.

Could be worse. An eagle once mistook Aeschylus's bald head for a rock and dropped a tortoise on it (expecting the rock to smash the tortoise shell), killing Aeschylus. https://www.goldencharter.co.uk/news-and-info/2017/six-stran... .

what a tragedy!

It's a hard task for young kids or anyone not used to watching sports. Ever watch a new sport with a child? They frequently lose sight/track of the ball/puck/etc.

I'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.

Actually not the original co-ordinates, but a point arbitrarily decided by a panel. I suspect that's where most people went wrong!
