Vision and the Visual System

Davida Teller worked on this book until 2009. At that time her health prevented her from finishing and she passed away in 2011. The book was well along but incomplete. I have edited the book with the goal of making it accessible to others. As much as possible, my approach was to preserve Davida's voice by removing material that was incomplete rather than adding material. This printing includes all of the text, figures and references for the 26 chapters written by Davida. Many of the figures are hand drawn or modified from previously published figures with citation of the source. Permission to reproduce these materials will be requested when the book is complete. I intend to do one more round of editing of this book and send it to the publisher in July 2014. For those reading it, please tell me about any errors you find ([email protected]). I do not expect to do any major revisions, but I do wish to remove as many errors as possible. For those of you that have seen the version distributed in 2013, the major revisions are in the last 3 chapters. The editing of this book was done together with my friends and colleagues. The first round of copyediting, gathering figures, and finding references was done by my student Serap Yigit-Elliott. at the direction of its chair, Professor Sheri Mizumuri. The second round of editing was done in conjunction with teaching " Davida's vision course " at the University of Washington in the summer of 2012. I thank all of the students of that course for their suggestions. The third round of editing was aided by comments and support from many colleagues including Pereverzeva read every chapter and made detailed comments. Special thanks goes to my wife, Zelda Zabinsky, for her suggestions and enduring support. In addition, I thank Davida's husband, Tony Young, for his encouragement and help assembling the materials. Most importantly, I thank Davida Teller for her trust in allowing me to edit her work. Preface Vision science can be defined as the study of vision, the visual system, and the relations between the two. When we study vision, we use psychophysical and perceptual techniques to describe what and how well we see: how good are our spatial and temporal resolution? What is our color vision like? What are the properties of motion perception, form perception, object recognition? When we study …
