Some people see human shapes in trees, others recognize facial features in automobiles. Often we see faces in objects while they actually are not there. This phenomenon is know as pareidolia. The brain is looking for patterns, like human faces, and sometimes it sees them when they are not there.
July this year, Google released its DeepDream algorithms. The software is build to recognize patterns and to learn to identify and categorize images. The program can also enhance the patterns it sees. The output resembles the phenomenon of pareidolia in humans. The software sees animals and faces in everything.
Synth musician Pouff recently released a video clip made with the DeepDream program. The video turns a normal stroll through the supermarket into a psychedelic dream (or nightmare) of algorithmic pareidolia.
