From the reviews:

"This large work by Szeliski (Microsoft Research), an experienced computer vision researcher and instructor, contains hundreds of glossy color photos that illustrate the variety of techniques used to analyze and interpret images. . It is suitable for teaching a senior-level undergraduate course in computer vision or graduate courses covering the more demanding material. Its primary use will be as a general reference to the fundamental techniques and recent research literature for graduate students, faculty/researchers, and professionals. Summing Up: Recommended. Upper-division undergraduates and above." (C. Tappert, Choice, Vol. 48 (9), May, 2011)

"The aim of this book is to provide a course in computer vision for undergraduate students in computer science or electrical engineering. . The focus is on algorithms and applications. . The mathematics covered is nicely presented . . Each chapter contains exercises and references to additional reading. . The book also contains many references to resources on the Internet." (Lisbeth Fajstrup, Zentralblatt MATH, Vol. 1219, 2011)

"The main interests of Richard Szeliski''s book is to give a . up-to-date overview of the state of the art. . a valuable resource for teaching computer vision at either the undergraduate or graduate level. . an interesting read for any student or engineer who wants a broad introduction to the field of computer vision. . From a teaching point of view, the book is a valuable resource, offering an extended list of exercises, project proposals, and appealing applications of computer vision techniques."
