Detection of Outer Rotations on 3D-Vector Fields with Iterative Geometric Correlation and its Efficiency
Roxana Bujack, Gerik Scheuermann, Eckhard Hitzer
Correlation is a common technique for the detection of shifts. Its generalization to the multidimensional geometric correlation in Clifford algebras has been proven a useful tool f…
Detection of Total Rotations on 2D-Vector Fields with Geometric Correlation
Roxana Bujack, Gerik Scheuermann, Eckhard Hitzer
Correlation is a common technique for the detection of shifts. Its generalization to the multidimensional geometric correlation in Clifford algebras additionally contains informati…

A General Geometric Fourier Transform Convolution Theorem
Roxana Bujack, Gerik Scheuermann, Eckhard Hitzer
The large variety of Fourier transforms in geometric algebras inspired the straight forward definition of ``A General Geometric Fourier Transform`` in Bujack et al., Proc. of ICCA9…
A General Geometric Fourier Transform
Roxana Bujack, Gerik Scheuermann, Eckhard Hitzer
The increasing demand for Fourier transforms on geometric algebras has resulted in a large variety. Here we introduce one single straight forward definition of a general geometric…
Convolution products for hypercomplex Fourier transforms
Roxana Bujack, Hendrik De Bie, Nele De Schepper +1
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 a…
