1. Luminescence Properties of ZnO Nanostructures and Their Implementation as White Light Emitting Diodes (LEDs)
Sammanfattning : In this thesis, luminescence properties of ZnO nanostructures (nanorods, nanotubes, nanowalls and nanoflowers) are investigated by different approaches for possible future application of these nanostructures as white light emitting diodes. ZnO nanostructures were grown by different growth techniques on different p-type substrates. LÄS MER
2. Salient Region Detection Methods with Application to Traffic Sign Recognition from Street View Images
Sammanfattning : In the computer vision community, saliency detection refers to modeling the selective mechanism in human visual attentions. Outputs of saliency detection algorithms are called saliency maps, which represent conspicuousness levels of different scene areas. LÄS MER
3. Real-Time Algorithms and Intersection Test Methods for Computer Graphics
Sammanfattning : In real-time computer graphics applications, at least three major forces are in conflict, namely, rendering speed, the level of realism, and interactivity. Therefore this thesis focuses on real-time algorithms that enhance the realism while maintaining high rendering speed, and on fast intersection test methods in order to speed up, for example, collision detection, picking processes and ray tracing. LÄS MER
4. Efficient rendering of semi-transparent geometry in real-time
Sammanfattning : Rendering images of semi-transparent geometry representing e.g. LÄS MER
5. Color Emotions in Large Scale Content Based Image Indexing
Sammanfattning : Traditional content based image indexing aims at developing algorithms that can analyze and index images based on their visual content. A typical approach is to measure image attributes, like colors or textures, and save the result in image descriptors, which then can be used in recognition and retrieval applications. LÄS MER
