Algebra of dual quaternions in image analysis
Hrubý, Jan ; Návrat, Aleš (referee) ; Hrdina, Jaroslav (advisor)
This work has two goals. Firstly it is to acquaint the reader with the classical use of quaternions and dual quaternions in geometry. Secondly the generalization of the Fourier transform into the set of dual quaternions. At first it goes into algebraic properties and structure of quaternions and ways of their inscriptions. Later dual numbers are introduced and consecutively with their help dual quaternions. Then the work deals with description of rotations and translations using quaternions and dual quaternions, that enable their easy description. Finally the discreet dual quaternion Fourier transform is defined, and for its effective calculation the algorithm is derived, which is then brought into effect as a code in program environment MATLAB.

Curves in D^3_1
Navrátil, Dušan ; Doupovec, Miroslav (referee) ; Kureš, Miroslav (advisor)
The Bachelor thesis deals with research on curves in three-dimensional space with Lorentzian inner product. The emphasis is on detailed analysis of dual numbers and dual Lorentzian space properties. Main part of this work is focused on dual functions, their differentiability, both arc length reparametrization and Frenet equations of dual curves and examples of such a curves. Within this work, many statements were derived generalizing from Minkowski space. Properties of dual rectifying curves were described in last section and finally we showed relation between these curves, dual unit spherical curves and ruled surfaces in Minkowski space.
