Directional image representations using nonseparable lifting
… This thesis demonstrates a method to create a directional image representation with compact spatial support which is not limited to a single dimension. Within the lifting framework of perfect reconstruction filter banks, sparse representation requires prediction filters able to adapt to the …

Multiple Antenna Terminals in Realistic Environments - A Composite Channel Modeling Approach
… channel models that take into account also the directional domain of the propagation channel. In this thesis we investigate, validate and propose a practical approach to wireless channel modeling and, particularly, to mobile communication systems. For this we make the assumption that the channel …

Human Visual Navigation: Effects of Visual Context, Navigation Mode, and Gender
… Participants were able to perform the task, but directional estimates showed characteristic errors, which can be explained with a model of distance misperception on the outbound roads of the route. Display and route layout parameters had very strong effects on performance. Gender and navigation …
