In this book signals or images described by functions whose number of arguments varies from one to five are considered. This arguments can be time, spatial dimensions, or wavelength in a polychromatic signal. The book discusses the basics of mathematical models of signals, their transformations in technical pre-processing systems, and criteria of the systems quality. The models are used for the solution of practical tasks of system analysis, measurement and optimization, and signal restoration. Several examples are given.

Multidimensional or spatio-temporal signals are important in image processing and television. This book presents the mathematical methods for the processing of multidimensional signals. Applications in system analysis, measurement and optimization, and signal restoration are described. Some examples of applications are given. Includes supplementary material: sn.pub/extras
