Image Processing: Tensor Transform and Discrete Tomography with MATLAB ®
TL;DR: In this paper, the authors present several new ideas, concepts, and methods, many of which have not been published elsewhere, for image reconstruction on the Cartesian lattice of computed tomography (CT) scans.
Proceedings ArticleDOI
Nonlinear Approach Of Construction of Fast Unitary Transforms
TL;DR: A novel approach to compose discrete unitary transforms that are induced by given input signals and applied over other signals, which are parameterized and fast, have simple forms of decomposition, and can be applied for signals of any length.
Proceedings ArticleDOI
Discrete unitary transforms generated by moving waves
TL;DR: A new class of discrete heap transforms which are unitary energy-preserving transforms and induced by input signals are described, which have a simple form of composition and fast algorithms for any size of processed signals.
Proceedings ArticleDOI
Method of Sliding Norm Transforms For Peak-to-Average Power Reduction In OFDM Systems
TL;DR: This paper presents a novel approach to compose nonlinear invertible transforms that can be used effectively in communication systems, as well as in signal and image processing.
