Convolution Products for Hypercomplex Fourier Transforms [PDF]

Journal of Mathematical Imaging and Vision, 2013
Hypercomplex Fourier transforms are increasingly used in signal processing for the analysis of higher-dimensional signals such as color images. A main stumbling block for further applications, in particular concerning filter design in the Fourier domain, is the lack of a proper convolution theorem.

Approximation of Integral Operators Using Product-Convolution Expansions [PDF]

Journal of Mathematical Imaging and Vision, 2016
We consider a class of linear integral operators with impulse responses varying regularly in time or space. These operators appear in a large number of applications ranging from signal/image processing to biology.

Relationships among transforms, convolutions, and first variations

International Journal of Mathematics and Mathematical Sciences, 1999
In this paper, we establish several interesting relationships involving the Fourier-Feynman transform, the convolution product, and the first variation for functionals F on Wiener space of the form F(x)=f(〈α1,x〉,…,〈αn,x〉),

Fast hash functions and convolution product

Journal of Mathematical Cryptology, 2014
We propose a new simple and efficient family of hash functions based on matrix-vector multiplications with a competitive software implementation. The hash design combines a hard mathematical problem based on solving a system of linear equations with ...
