As humans, it’s only natural to take a look at the sky and perceive to see an object, a face, an animal. Computers, too, are capable of this perception. However, they may be capable of finding things that the human eye can’t, or just might not notice. In a project called “Cloud Face“, Seoul, South Korea-based Shin Seung Back and Kim Yong Hun of aptly-named ‘Shinseungback Kimyonghun‘ have pointed cameras up at the sky and let complex algorithms detect faces in the passing clouds. The results, to say the least, are rather interesting. The project aims to “examine the relation between computer vision and human vision”.
