This is pretty neat, I wonder if it has to be human trained or if there's some sort of computer vision algorithm determining pointing.


After looking into to the code I found out that this app is made by using Voronoi diagrams. [1]

The actual positions are saved in a json file. [2]

Yes, but how did the author create that .json file? Manually or using some ML algorithm?


What would be interesting is if new images were periodically added and the grid adjusted in response.
