Advances in electronics and electron physics. Volume 51

This volume contains review articles covering a broad range of topics in image processing and analysis. The topics covered include image analysis - which has united and harmonized a host of heterogeneous material; contemporary approaches to the Fourier transform; number theoretic transforms, which are particularly attractive for discrete, finite signals; the use of the Wigner distribution - which encodes both spatial and spectral information, for image filtering; and applications of the concept of information energy. These up-to-date surveys are intended to provide the reader with access to the latest results in the extremely active field of image science.
