The main challenge of an augmented reality system is to obtain perfectalignment between real and virtual objects in order to create the illusionthat both worlds coexist. To that end, the position and orientation of theobserver ...

<p>It is widely accepted that a reform in medical teaching must be made to meet today s high volume training requirements. Receiving pre-training in a core set of surgical skills and procedures before novice practitioners ...

Selection is one of the fundamental tasks in virtual reality applications and the initial task for most common user's interactions in a virtual environment. In this thesis we analyze major factors influencing selection ...

A new trend Web service ecosystems for Service-Oriented Architectures (SOAs) and Web services is emerging. Services can be offered and traded like products in these ecosystems. The explicit formalization of services' ...

Symmetry is an essential property of a shapes' appearance and presents a source of information for structure-aware deformation and model synthesis. This thesis proposes feature-based methods to detect symmetry and regularity ...

In recent times we are witnessing a steep increase in the availability of data comingfrom real-life environments. Nowadays, virtually everyone connected to the Internetmay have instant access to a tremendous amount of data ...

Global illumination (GI) rendering plays a crucial role in the photo-realistic rendering of virtual scenes. With the rapid development of graphics hardware, GI has become increasingly attractive even for real-time ...

Creating photo-realistic images has been one of the major goals in computer graphics since its early days. Instead of modeling the complexity of nature with standard modeling tools, imagebased approaches aim at exploiting ...

The extraction and visualization of information from volume data constitute important research avenues in computer graphics and imaging. The rapid development of GPUs with increasing computational power has made it possible ...

Nowadays huge digital models are becoming increasingly available for a number of different applications ranging from CAD, industrial design to medicine and natural sciences. Particularly, in the field of medicine, data ...
