Cloud Face, 2012 by Kim Yong Hun_
“Human sees figures in clouds: animals, faces and even god. This kind of perception also appears in computer vision. Face-detection algorithms sometimes find faces that are not. It is because human’s knowledge of a face and understanding of human vision mechanisms affect the development of the computer vision.
‘Cloud Face’ is a collection of cloud images that are recognized as human face by a face-detection algorithm. It is a result of computer’s vision error, but they look like faces to human eyes, too. This work attempts to examine the relation between computer vision and human vision.” – Kim Yong Hun
