ABSTRACT
Vision is perhaps the most essential of human senses. A large part of human brain is devoted to vision, which explains the enormous complexity of the human visual system. The human visual system can be subdivided into two major components: the eyes, which capture light and convert it into signals that can be understood by the nervous system, and the visual pathways in the brain, along which these signals are transmitted and processed. This chapter discusses the anatomy and physiology of these components as well as a number of phenomena of visual perception that are of particular relevance to digital imaging.
