Abstract: qIn this thesis I will examine the relations between turbulence as found in physical systems and turbulence in optic flow fields. I will record some image sequences of a theoretically well understood turbulent physical system and from these image sequences I will examine the relations between the optic flow of the image sequences and the physical parameters of the turbulent system. I will examine the image sequences at different scales using the theory of linear Gaussian scale-space, because linear Gaussian scale-space has proven to be a valuable tool in digital image processing and because the physics of turbulence can be explained through scaling properties of the turbulent flow. From these analyses I hope to be able to describe the theoretical relations between turbulence in optic flow fields and turbulence in physical systems. I have obtained the permission to borrow and use equipment and experimental setup for the recording of the image sequences by Preben AlstrAcm and Mogens Levinsen from the Niels Bohr Institute (NBI). This abstract is a translated version of the description of the project ('Arbejdsbeskrivelse'), delivered to the administration of DIKU at the start of this project.qAbstract: aquot;In this thesis I will examine the relations between turbulence as found in physical systems and turbulence in optic flow fields.
