This book is largely based on the computer vision courses that I have co-taught at the University of Washington (2020, 2008, 2005, 2001) with Steve Seitz and Harpreet Sawhney and at Stanford (2003) with David Fleet.

If you're curious about the process that went into writing my book, I did an interview with Computer Vision News (March 2022).

First edition

You can still download the first edition or potentially purchase it online. The first edition is also available in Chinese and Japanese (translated by Prof. Toru Tamaki).


If you have any comments or feedback on the book,
please send me e-mail. Once I have accumulated enough suggestions, I will post an updated draft with the corrections/suggestions as PDF comments.

Slide sets and lectures

There are no official slide sets to go with the book, but please feel free to look at the University of Washington CSE 576 (Graduate Computer Vision) (2020 and 2008 versions) slides that Steve Seitz and I have put together.
