1. 1. Evaluation of Performance and Image Quality for Voxel Cone Tracing

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Johannes Finn; [2022]
   Keywords : computer graphics; voxel cone tracing; voxel-based rendering;

   Abstract : Voxel cone tracing (VCT) is a rendering method designed to approximate global illumination in a fast and efficient way. Global illumination means to render not only the direct lighting of a scene but also light from indirect sources, simulating how light in the real-world tend to bounce around and illuminate even the areas that are occluded from a direct light source.

3. 2. Level 1 processing  algorithms of MicroCarb  microsatellite : Performance assessment of ISRF in-flight estimation through new algorithms

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Quentin Taupin; [2021]
   Keywords : ;

   Abstract : Facing global warming and its dramatic consequences, it is now of the utmost urgency to improve our understanding of the carbon cycle mechanisms through which global climate change unfolds. The MicroCarb mission will allow to accurately monitor CO2 global sources and sinks over the entire surface of the Earth. READ MORE

4. 3. Indoor scene verification : Evaluation of indoor scene representations for the purpose of location verification

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Filip Finfando; [2020]
   Keywords : computer vision; perceptual similarity; visual place recognition; indoor scene localization; deep neural networks; datorseende; perceptuella likheter; visuell platsigenkänning; inomhusbild lokalisering; djupa neuronnät;

   Abstract : When human’s visual system is looking at two pictures taken in some indoor location, it is fairly easy to tell whether they were taken in exactly the same place, even when the location has never been visited in reality. It is possible due to being able to pay attention to the multiple factors such as spatial properties (windows shape, room shape), common patterns (floor, walls) or presence of specific objects (furniture, lighting).

5. 4. Radiosity for Real-Time Simulations of Highly Tessellated Models

   University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

   Author : Henrik Edström; [2016-05-27]
   Keywords : radiosity; hierarchical radiosity global illumination; light mapping; face cluster radiosity; volume cluster radiosity; texture atlas.;

   Abstract : The accurate simulation of light is one of the most important aspects of computer graphics. Radiosity is a physically-based method that can generate view-independent solutions of the light scattering in a scene. READ MORE

6. 5. Character recognition in natural images : Testing the accuracy of OCR and potential improvement by image segmentation

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

   Author : Matija Kraljevic; [2016]
   Keywords : ;

   Abstract : In recent years, reading text from natural images has gained renewed research attention. One of the main reasons for this is the rapid growth of camera-based applications on smart phones and other portable devices. READ MORE
