 Here in the U.S., it's a red hand, which is the don't walk signal, and then a white walking man, which is the walk signal. In Europe, Japan, or similar places, it's just like a red guy, which is the don't walk, and then a green walking man, which is the walk signal. And they're on top of each other instead of one square pedestrian signal. So it's just like a whole different view and different colors, which the AI needs to learn, of course. And how accurate is the app?
