How Do We See Art: An Eye-Tracker Study

We describe the pattern of fixations of subjects looking at figurative and abstract paintings from different artists (Molina, Mondrian, Rembrandt, della Francesca) and at modified versions in which different aspects of these art pieces were altered with simple digital manipulations.

It is found that face recognition alone needs far fewer pixels than people normally thought. However, more pixels are needed f...
