  1. 1. Planet-NeRF : Neural Radiance Fields for 3D Reconstruction on Satellite Imagery in Season Changing Environments

    University essay from Linköpings universitet/Datorseende

    Author : Erica Ingerstad; Liv Kåreborn; [2024]
    Keywords : NeRF; Neural Radiance Field; Satellite Imagery; Machine Learning; Deep Learning;

    Abstract : This thesis investigates the seasonal predictive capabilities of Neural Radiance Fields (NeRF) applied to satellite images. Focusing on the utilization of satellite data, the study explores how Sat-NeRF, a novel approach in computer vision, per- forms in predicting seasonal variations across different months. READ MORE

  3. 2. Exploration of Alternative Image Representation Using Signed Distance Functions

    University essay from Lunds universitet/Institutionen för designvetenskaper

    Author : Jakub Olejnik; [2023]
    Keywords : computer graphics; SDF-based rendering; machine learning; Technology and Engineering;

    Abstract : This project leverages the core concepts of differentiable rendering to find alternative representation of images using geometric primitives rendered with Signed Distance Functions. By utilising gradient-descent-based methods it is possible to find optimal parameters of rendered primitives to create high-quality reconstruction. READ MORE

  4. 3. Skyline Delineation for Localization in Occluded Environments : Improved Skyline Delineation using Environmental Context from Deep Learning-based Semantic Segmentation

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

    Author : Kyle William Coble; [2023]
    Keywords : Skyline delineation; Skyline detection; Semantic segmentation; Terrain based navigation; Digital elevation models; Uncrewed surface vessel; Planetary exploration robots; Horisont avgränsning; Horisont upptäckt; Semantisk segmentering; Terrängbaserad navigering; Digitala höjdmodeller; Obemannat ytfartyg; Planetariska utforskningsrobotar;

    Abstract : This thesis addresses the problem of improving the delineation of skylines, also referred to as skyline detection, in occluded and challenging environments where existing skyline delineation methods may struggle or fail. Delineated skylines can be used in monocular camera localization methods by comparing delineated skylines to digital elevation model data to estimate a position based on known terrain. READ MORE

  5. 4. Phong Grass: A dynamic LOD approach to grass rendering

    University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

    Author : Oliver Klingspor; [2023]
    Keywords : Grass rendering; Level-of-detail; Phong tessellation;

    Abstract : Background: Recreating nature in a virtual environment comes with many aspects and challenges. Grass rendering is a part of this area, and both performance and visual results must be taken into consideration. A common optimization approach is through static level-of-detail (LOD), however, a certain visual loss comes with the use of this. READ MORE

  6. 5. 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.
