1. Perceptual Surface Reconstruction
Sammanfattning : How does the brain transform the 2-D light arrays in our eyes into a meaningful 3-D description of surfaces around us? What assumptions does the visual system make about the world when information is incomplete? And how are these assumptions computationally expressed in this perceptual reconstruction process? These questions, and other aspects of binocular depth perception are analysed from a theoretical and computational perspective, as well as through empirical investigations. In paper one, the fundamentals of stereopsis are briefly reviewed, and the difficulties related with resolving the (stereo) correspondence problem are particularly discussed. LÄS MER
2. Radome Diagnostics: utilizing Source Reconstruction based on Surface Integral Representations
Sammanfattning : In this thesis, an inverse source reconstruction method with great potential in radome diagnostics is presented. A radome is a cover that encloses an antenna in order to protect it from environmental influences. LÄS MER
3. Atomic and Electronic Structure of III-V Semiconductor Surfaces
Sammanfattning : The atomic and electronic structure of clean and Cs-perturbed III-V semiconductors was studied by angle-resolved photoelectron spectroscopy (ARPES), surface core level spectroscopy (SCLS), and scanning tunneling microscopy (STM). The work can be divided into three parts, dealing with low-index sur-faces, high-index surfaces, and special features of InAs. LÄS MER
4. Extensions and Applications of Affine Shape
Sammanfattning : 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. LÄS MER
5. Finger Joint Reconstruction with Rib Perichondrium
Sammanfattning : Difficulties in repairing and reconstructing articular cartilage damaged by trauma or disease remain unsolved and are one of the major challenges confronting orthopedic and hand surgeons in their clinical work. Relevant research has not adequately described the long-term clinical results, nor has it made a direct comparison to implant surgery after finger joint reconstruction with rib perichondrium. LÄS MER
