1. 1. Luminescence Properties of ZnO Nanostructures and Their Implementation as White Light Emitting Diodes (LEDs)

   Författare :Naveed ul Hassan Alvi; Magnus Willander; Omer Nour; Vladimir V. Mitin; Linköpings universitet; []
   Nyckelord :Nanotechnology; Zinc oxide; nanostructures; luminescence; LEDs; color rendering; NATURAL SCIENCES; NATURVETENSKAP;

   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

3. 2. Salient Region Detection Methods with Application to Traffic Sign Recognition from Street View Images

   Författare :Keren Fu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; normalized cut; traffic sign recognition; saliency propagation; color distribution; continuous conditional random field; manifold; Salient region detection; adaptive graph edge weights; color contrast; geodesics;

   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

4. 3. Real-Time Algorithms and Intersection Test Methods for Computer Graphics

   Författare :Tomas Möller; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; texture; ray tracing; radiosity; color; three-dimensional graphics and realism; virtual reality; algorithms; shadowing; shading;

   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.

5. 4. Efficient rendering of semi-transparent geometry in real-time

   Författare :Erik Sintorn; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Rendering images of semi-transparent geometry representing e.g. LÄS MER

7. 5. Color Emotions in Large Scale Content Based Image Indexing

   Författare :Martin Solli; Reiner Lenz; Björn Kruse; Stephen Westland; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   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
