For courses in Image Processing and Computer Vision.
For years, Image Processing has been the foundational text for the study of digital image processing. The book is suited for students at the college senior and first-year graduate level with prior background in mathematical analysis, vectors, matrices, probability, statistics, linear systems, and computer programming. As in all earlier editions, the focus of this edition of the book is on fundamentals.
The 4th Edition is based on an extensive survey of faculty, students, and independent readers in 5 institutions from 3 countries. Their feedback led to epanded or new coverage of topics such as deep learning and deep neural networks, including convolutional neural nets, the scale-invariant feature transform (SIFT), maimally-stable etremal regions (MSERs), graph cuts, k-means clustering and superpiels, active contours (snakes and level sets), and eact histogram matching. Major improvements were made in reorganising the material on image transforms into a more cohesive presentation, and in the discussion of spatial kernels and spatial filtering.
- Timely, highly readable, and heavily illustrated with numerous examples of practical significance.
- NEW! This edition contains 5 new images, 35 new drawings, and new exercises.
- Focuses on the fundamental material whose scope of application is not limited to the solution of specialised problems
- Updated with feedback from an extensive survey that involved faculty, students, and independent readers of the book in 5 institutions from 3 countries.
- UPDATED! A complete update of the image pattern recognition chapter to incorporate new material on deep neural networks, back propagation, deep learning, and, especially, deep convolutional neural networks.
- EXPANDED! Coverage of feature extraction, including the Scale Invariant Feature Transform SIFT, MSERs, and corner detection.
- NEW! Coverage of graph cuts and their application to segmentation.
- NEW! A discussion of superpiels and their use in region segmentation.
- NEW! An introduction to segmentation using active contours (snakes and level sets).
- NEW! Material related to each histogram matching.
- EXPANDED! Coverage of the fundamentals of spatial filtering, image transforms, and finite differences with a focus on edge detection.
- NEW! Two new chapters:
- A chapter dealing with active contours for image segmentation, including snakes and level sets.
- A chapter that brings together wavelets, several new transforms, and many of the image transforms that were scattered throughout the book.
- NEW! MATLAB projects, located at the end of every chapter and are structured in a unique way that gives instructors significant flexibility in how projects are assigned.
- The MATLAB functions required to solve all the projects in the book are provided in executable, p-code format which makes it possible for projects to be assigned solely for the purpose of experimenting with image processing concepts, without having to write a single line of code.
