Dictionary of Computer Vision and Image ProcessingBob Fisher, Kenneth Dawson-Howe, Andrew Fitzgibbon, Craig Robertson and Emanuele Trucco.
This dictionary arose out of a continuing interest in the resources needed by beginning students and researchers in the fields of image processing, computer vision and machine vision (however you choose to define these overlapping fields). As instructors and mentors, we often found confusion about what various terms and concepts mean for the beginner. To support these learners, we have tried to define the key concepts that a competent generalist should know about these fields. The results are definitions for more than 2500 terms.
This is a dictionary, not an encyclopedia, so the definitions are necessarily brief and are not intended to replace a proper textbook explanation of the term. We have tried to capture the essentials of the terms, with short examples or mathematical precision where feasible or necessary for clarity. Further information about many of the terms can be found in the references below. These are mostly general textbooks, each providing a broad view of a portion of the field. Some of the concepts are also quite recent and, although commonly used in research publications, have not yet appeared in mainstream textbooks. Thus this book is also a useful source for recent terminology and concepts.
Certainly there are some missing concepts, but we have scanned both textbooks and the research literature to find the central and commonly used terms. Many additional terms also arose as part of the definition process itself.
Although the dictionary was intended for beginning and intermediate students and researchers, as we developed the dictionary it was clear that we also had some confusions and vague understandings of the concepts. It also surprised us that some terms had multiple usages. To improve quality and coverage, each term was reviewed during development by at least two people besides its author. We hope that this has caught any errors and vagueness, as well as reproduced the alternative meanings. Each of the co-authors is quite experienced in the topics covered here, but it was still educational to learn more about our field in the process of compiling the dictionary. We hope that you find using the dictionary equally valuable.
While we have strived for perfection, we recognize that we might have made some errors or been insufficiently precise. Hence, there is a web site where errata and other materials can be found: http://homepages.inf.ed.ac.uk/rbf/CVDICT/. If you spot an error, please email us: .
To help the reader, terms appearing elsewhere in the dictionary are hyperlinked. We have tried to be reasonably thorough about this, but some terms, such as 2D, 3D, light, camera, image, pixel and color were so commonly used that we decided to not cross-reference these.

We have tried to be consistent with the mathematical notation:
