Photo Mosaics with Nearest Neighbors: Machine Learning for Digital Art

Technological innovation is increasing at a rapid pace and has made digital storage extremely cheap and accessible. Additionally, most people now have phones with cameras that are able to capture high quality images. The majority of images taken are viewed a few times and then sent to sit on a hard drive or some cloud storage service. I am no different, and since I had some extra time during the COVID-19 lockdowns, I came up with some software to give the photos in people's libraries a second life. This software creates photo mosaics.
