Produktbeschreibung

Digital Functions and Data Reconstruction: Digital-Discrete Methods provides a solid foundation to the theory of digital functions and its applications to image data analysis, digital object deformation, and data reconstruction. This new method has a unique feature in that it is mainly built on discrete mathematics with connections to classical methods in mathematics and computer sciences.

Digitally continuous functions and gradually varied functions were developed in the late 1980s. A. Rosenfeld (1986) proposed digitally continuous functions for digital image analysis, especially to describe the "continuous" component in a digital image, which usually indicates an object. L. Chen (1989) invented gradually varied functions to interpolate a digital surface when the boundary appears to be continuous. In theory, digitally continuous functions are very similar to gradually varied functions. Gradually varied functions are more general in terms of being functions of real numbers; digitally continuous functions are easily extended to the mapping from one digital space to another.

This will be the first book about digital functions, which is an important modern research area for digital images and digitalized data processing, and provides an introduction and comprehensive coverage of digital function methods. Digital Functions and Data Reconstruction: Digital-Discrete Methods offers scientists and engineers who deal with digital data a highly accessible, practical, and mathematically sound introduction to the powerful theories of digital topology and functional analysis, while avoiding the more abstruse aspects of these topics.

Rezensionen

"The main topic of the book is data reconstruction, i.e. curve or surface fitting to a given digital function. This is important for various engineering applications, especially image processing... The present book focuses on the concept of a gradually varied function (GVF) and its applications... The author discusses in §11.3 the 'natural' continuity and smoothness. According to him, such notions are not absolute as in the conventional theory in pure mathematics, but rather depend on the scale to be considered. This is an interesting opinion... This is a huge collection of the author's works on the practical applications of gradually varied functions. It is also a nice textbook for curve/surface fitting." (S. Hitotumatu, Mathematical Review, MR3013361)

"The book under review provides an introduction and comprehensive survey of digital function methods and their applications to image data analysis and data reconstruction. This is the first book about this important topic. It is mainly written for graduate students in computer science and for researchers who are interested in digital geometry, computer graphics, and data reconstruction... Without any doubt, this book will be a valuable source of information on digital functions and its applications." (Manfred Tasche, Zentralblatt MATH, Zbl 06102122)
