1. The three-dimensional normal-distributions transform : an efficient representation for registration, surface analysis, and loop detection
Abstract : This dissertation is concerned with three-dimensional (3D) sensing and 3D scan representation. Three-dimensional records are important tools in several disciplines; such as medical imaging, archaeology, and mobile robotics. READ MORE

2. Moisture-induced stress and distortion of wood : A numerical and experimental study of wood's drying and long-term behaviour
Abstract : With the current advances made in three-dimensional modelling of wood, it is possible to provide an overall picture of moisture flow, and moisture-induced stress and deformations, whereas previously, experiments only provided local measurements. The main aim of the doctoral thesis is to investigate the possibilities of the developed three-dimensional numerical model to predict the behaviour of wood when simultaneously exposed to a mechanical load and a particular climate.

3. Global Shape Description of Digital Objects
Abstract : New methods for global shape description of three-dimensional digital objects are presented. The shape of an object is first represented by a digital surface where the faces are either triangles or quadrilaterals. READ MORE

4. Virtual three-dimensional analysis of digitized dental impressions and stone replicas
Abstract : In response to increasing patient awareness of esthetic dental rehabilitation, the preference today is for all-ceramic restorations, which show superior biocompatibility and similar light characteristics to the natural tooth. The fit of a dental restoration depends on quality throughout the entire manufacturing process. READ MORE

5. Extensions and Applications of Affine Shape
Abstract : A central problem in computer vision is to reconstruct the three-dimensional structure of a scene from a set of two-dimensional images. Traditionally this is done by extracting a set of characteristic points in the scene and to compute a reconstruction of these points. READ MORE
