Customer Reviews

An unusually clear book -- and great for OCR researchers.

This nifty book is unusual in several respects: it is written in an extremely clear and simple style; it presents good clear code, both in print and on the accompanying CD; and it presents a variety of different methods for achieving each given goal. For example, the book presents a half-dozen different algorithms (usually with code) for edge-detection, for thresholding, and for skeletonization. For the most part, the book does a good job of explaining the relative merits or suitabilities of the different algorithms. It's important to say, though, that this book is not a comprehensive introduction to image processing issues and algorithms (such as Gonzales & Woods), nor is it a soup-to-nuts cookbook of code (such as Myler & Weeks' admittedly dated "Pocket Handbook"). Although the book is written in a style that students could understand, I wouldn't recommend it as a first book for novice students. It would be better suited to a non-specialist who nevertheless needs to accomplish something specific -- like thresholding or edge-detection -- in short order, and with an algorithm that's tuned to their particular application. One last thing: this book will be VERY MUCH appreciated by anyone seeking a foundation in optical character recognition.

Outstanding source of implementations of image processing algorithms

This book is a great source of code for the implementations of common and not so common algorithms used in image processing and computer vision. It is not meant to be a textbook on either subject. For that I suggest you turn to "Digital Image Processing" by Gonzalez and Woods for the subject of image processing and to "Computer Vision" by Linda Shapiro for computer vision. The book starts out with the treatment of a common subject - edge detection - and provides code for various edge detectors including Canny, Shen-Casten, and Marr-Hildreth. Chapter 2 does a pretty good job of explaining digital morphology, the various operations, and their uses. Chapter 3 has a very brief introduction to gray-level segmentation, and then jumps into more advanced topics such as the method of iterative selection, entropy, fuzzy logic methods, and the method of Chow and Kaneko, among others. Most of the methods here are somewhat mathematically involved, and the author does a pretty good job of explaining the mathematics and showing resulting images that show the strengths of each method. Chapter 4 is about the calculation and use of texture in image processing and computer vision. Again, the mathematics here can get involved and equations and illustrations are included to help make the concepts clear. Even fractal geometry and its use in texture is very briefly mentioned. Chapter 5 is one of my favorites, since it covers the topic of skeletonization, which is not commonly covered in most vision or image processing books. The most common method is mentioned first - that of the medial axis transform. This is followed by a discussion of iterative morphological methods and also the use of contours. Finally, the chapter is rounded out with an explanation of the Zhang-Suen/Stentiford/Holt combined method and accompanying code. This method usually produces the best combination of good visual results and computational efficiency. In Chapter 6, on image restoration, the author moves to the frequency domain and discusses the Fourier Transform, the FFT, and their uses in image restoration. The author provides his own image restoration system, the Eagle Restoration System, complete with code. Chapter 7, on wavelets, is a very brief and not too satisfying introduction to the topic. The author does provide some mathematics and some code for some basic transforms, but does not provide much in the way of motivation. Chapters 8 and 9, on optical character recognition and symbol recognition respectively, are two very good chapters on this subject. It provides the simple introductory information on recognizing printed alphabetic characters. It also talks about skew detection in the case of slanted lines of text. Chapter 9 expands the concepts with a very good section on neural networks and character recognition concluding with a system that recognizes printed music. Chapter 10, the final chapter of the book, was an OK introduction to genetic algorithms and evolutionary computing.

A great Scope

This book is very helpfull. Not only for image processing. An unsuspected use that I do to this book was use an algorithm for correct blurred images to revert effect of movil mean that produce a strain gage when one sense an compresion wave traveling throw an iron bar, and work very well. This book has an "honor place" in my library.

Excellent cook book of advanced IP techniques

At its best, this book is a wonderful cookbook of image processing techniques. For example the author's presentation of the Canny and Shen-Castan methods of edge detection is clear and detailed. Full C source is provided for this and all the other techniques discussed in the book. The book does not pretend to be a basic introduction to image processing -- if you do not have Castleman or Pratt or something similar on your bookshelf, you probably should not start by acquiring this book. A possible source of irritation for some readers will be the variation in depth of coverage of topics. For example, when the author discusses wavelets, the coverage is very scant and qualitative. It is well done, but quite different in kind from the aforementioned coverage of advanced edge detection techniques. Similarly, the author will cover specific aspects of image processing, such as motion blur for an image, in the context of a rather general discussion of image restoration. In short, the book seems to reflect the author's interests more than attempting to be an objective coverage of the current state of the art in image processing. Nonetheless, the high quality of the information that the author provides and the bibliography to further coverage of the given topics are well worth the price of the book. You just need to approach it on the author's terms rather than on a preconceived notion of what you should get out of the book.

A great "Imaging Recipes" book

A very good "imaging recipes" book. includes solutions to various IP/Vision problems ranging from low-level edge detection to high-level character recognition. Most of the algorithms are not presented in older books, which makes it a valueble source which replaces the tedious search through individual articles. Written in an "application oriented" approach, with lots of code snippets.
