This is the best, most understandable image processing book I ever read. It is the only image processing book I've ever read in which I could immediately turn the concepts into code (IDL). I spent most of a Christmas vacation thinking it was a novel I couldn't put down. That's about as good as it gets for a technical book! Well done, Gentlemen.

This book is the best textbook on image processing for senior/graduate students majoring in engineering or computer science. Although a knowledge of calculus and linear algebra is presumed, it is a very accessible textbook. Chapters one and two consist of very basic background information. The concepts of linearity, pixel distance measures, spatial versus gray scale resolution, and zooming and shrinking are explained. Chapter 3 is about image inhancement in the spatial domain, and includes discussions on contrast enhancement, histogram processing and equalization, and histogram matching. The idea of filtering images via an NxN kernel mask is also introduced. Chapter 4 is about filtering in the frequency domain. The 2D Fourier transform is introduced and it is explained how filtering can take place using this transform. Chapter five discusses image restoration. This includes Weiner filtering and minimum mean square error filtering. Chapter six discusses color image processing. This chapter discusses the various color spaces - RGB, CMYK, HSI, and how the transforms mentioned up to this point in the book can be performed in color. Chapter 7 is about wavelets and multiresolution processing. This chapter is a good solid presentation of wavelets and their usage in image processing. I would suggest that anyone interested in this subject start here before they read another book, since the presentation is clearer here than in books dedicated to the subject. Chapter 8 is about image compression. Basics of information theory are discussed, and lossy as well as lossless methods of compression are discussed. As a good follow-on to the previous chapter, the role of wavelets in compression is discussed. Chapter 9 discusses morphological image processing, which is that field of image processing that relies on the systematic "fattening" and "thinning" of edges to enhance images. Chapters 10,11, and 12 are a sort of introduction to computer vision topics. Chapter 10 discusses how to segment an image. Chapter 11 is about image descriptors that quantify segmented portions of an image. Chapter 12 is about object recognition and even has a short section on statistical classifiers. This book is a joy to read, and will make the topic of image processing very clear. There are plenty of diagrams, formulas, and equations listed. There are no examples to speak of, but algorithms are clearly specified so that I don't think that the book suffers because of the lack of examples. All engineering textbooks should be this well written. I particularly recommend this book as a reference for students and practitioners of robotics, video processing, and computer vision, since there are image processing considerations in all of these fields that this book will clarify.

This book is an excellent book for people who are new to Digital Image Processing and dont have any back ground on signal processing. The book explains the concept straight forward without confusing with signal processing concepts. The book gets a 5 star because it makes an effort to explain the image processing techniques in an orderly fashion starting with image acquisition and pixel brightness to object recognition in the final chapter. Excellent book for undergraduate and graduate Digital Image Processing students. A good reference book for people in image processing field.

The book is not well organized even though the organization is very important for such a book with a lot of contents.

Pleasure to read. Also, make sure u get ISBN: 0139353224.
Two-Dimensional Signal and Image Processing

The book gives a comprehensive treatment on image processing and covers the appropriate amount of information. The depth of materials was appropriate for someone already familiar with basic signal and probability theories. This is definitely the book to keep as reference if you plan to work in the area. An additional chapter on image reconstruction will be extra helpful.

This book gets better with ownership! It covers (well) many of the fundamental algorithms used in computer vision systems. I appreciate the book more today, than when I purchased it.

The book is fairly good but it lacks of examples

On this site, there are already good reviews of this book.
So I would like to post only a comment on the "Low Price" or "International" or "Indian" edition:

IT IS VERY VERY CHEAP and LOW QUALITY

The pages are almost transparent. While reading a face of a page, you can guess what is written on the other face. Definitely annoying.

This volume covers the waterfront of image processing from a reasonable introductory level. Refreshingly, it is much more than a cookbook. The authors pay attention to the physical principles that imaging and image manipulation are based on. With many quality images and examples, there is much for the less mathematically inclined to cut their teeth on while brushing up on their advanced math skills. The inclusion of many well chosen problems makes the book a valuable volume in a student's library. The book's associated web-site is a major bonus for the reader. I did find that some of the figure captions were challenging to interpret but the problem does not seem pervasive. Overall, I liked the book. It is a valuable addition to the image processing literature and to the image processing textbook selection.

I've been a senior researcher in Image Processing for more than 20 years, and my opinion of the book Digital Image Processing of Gonzalez and Woods, is that it is significantly superior to current books on image processing. The contents of the books are in the mainstream of work in this field, and the level of coverage is complete and written at a level that makes it an ideal textbook for seniors and first-year graduate students. The experience of the authors shows through in the way the material is presented and illustrated. The complementary web site is an outstanding teaching aid.

As a computer engineering senior with a strong interest in image processing and vision, I found this book very helpful.

The exemples are varied and interesting, the maths are easy to understand and the design is very clear. Obviously, it supposes the reader has some mathematical background, but nothing impossible for an undergraduate student.

It is also very complete: it goes from very basic image processing concepts (defining pixels, the RGB format) to more complex topics like pattern recognition and wavelet compression.

The book contains so much math formulas in the beginning that you probably think that you have to go back to your math books. If you have to get this book for your class then basically you are in trouble like me unless you are an expert. The book is not also very interesting in reading. Authors do have technical knowledge but have no clue how to hold the readers. Unless you are wasting your life for Image Processing only then I recommend getting this book otherwise "Big No-No" for everyone else.

This used to be the best textbook and reference source around, but even with the new edition it is dated, with poor coverage of things like video, wavelets and compression, and a terrible treatment of morphology. There's better books out there now, such as Tekalp's book on Video Processing and the Handbook of Image and Video Processing by Bovik etc. Still, pretty good treatment of the basic stuff.

I found this book to _not_ be very useful when it came to my Digital Image Processing class. Possibly it was do to it being my first experience in the subject, but the real world applications and concepts of the methods and algorithms are not explained in the book. Either are the algorithms themselves really. If you want the nuts and bolts math behind the concepts this is a good book. If you want something to explain to you what everything in DIP is all about (besides integrals and summations) and how to apply it, this book is poor.

After 9 years as a researcher in image analysis and pattern recognition, I still refer to this book on a regular basis. It give straightforward explainations of a broad range of algorithms. If I ever forget how to do something, I know I can look here and be reminded.

A good book, clear and easy to understand, and it is also easy to implement the algorithms mentioned in the book into a real world program. I used it as a text book in image processing class. Compared to other books in image processing, this book is a clear winner. The only drawback is the price. Other thing to remember is that this book is old enough in the ever-progressed image processing and computer graphic field.

A perfect image processing guide for beginners as well as advanced researchers. Very easy to read, and has nice examples. (It does not cover some very advanced image processing concepts.)
