ABSTRACT

This chapter provides a partial overview of what is known about visual perception in people. The emphasis is on aspects of human vision that are most relevant to computer graphics. The human visual system is extremely complex in both its operation and its architecture. The chapter provides key points, and it is important to avoid over generalizing from what is presented here. More in-depth treatments of visual perception can be found in B. A Wandell and S. E Palmer; R. L Gregory and S. Yantis provide additional useful information. A good computer vision reference such as D. A Forsyth and J. Ponce is also helpful. It is important to note that despite over 150 years of intensive research, our knowledge of many aspects of vision is still very limited and imperfect. Vision is generally agreed to be the most powerful of the senses in humans. Vision produces more useful information about the world than does hearing, touch, smell, or taste.
