Spatial Filtering

Description
The two pictures contain the same amount of low-frequency information, but extraneous high-frequency information has been filtered from the picture on the right. If you look at the pictures from across the room, they look identical. (From Harmon, L. D., and Julesz, B. Science, 1973, 180, 1191–1197. Copyright 1973 by the American Association for the Advancement of Science. Reprinted with permission.)
