  1. 16. Comparing 3D-Clipmaps and Sparse Voxel Octrees for voxelbased cone tracing

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Tomas Möre; Gustav Schneider; [2018]
    Nyckelord :;

    Sammanfattning : Voxel based cone tracing is a promising approach to approximate globalillumination for real-time applications. This technique utilizes a voxelfield approximating the original scene to retrieve the necessary radi-ance information during sampling. The simplest approach to creat-ing a voxel field is to use a 3D texture. LÄS MER

  3. 17. Real-time generation of kd-trees for ray tracing using DirectX 11

    Master-uppsats, Blekinge Tekniska Högskola

    Författare :Martin Säll; Fredrik Cronqvist; [2017]
    Nyckelord :Ray tracing; Kd-tree; acceleration; DirectX 11; compute shader;

    Sammanfattning : Context. Ray tracing has always been a simple but effective way to create a photorealistic scene but at a greater cost when expanding the scene. Recent improvements in GPU and CPU hardware have made ray tracing faster, making more complex scenes possible with the same amount of time needed to process the scene. LÄS MER

  4. 18. Foreground detection in specific outdoor scenes : A review of recognized techniques and proposed improvements for a real-time GPU-based implementation in C++

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Gustav Sandström; [2016]
    Nyckelord :foreground detection; background subtraction; background removal; real-time image processing;

    Sammanfattning : Correct insertion of computer graphics into live-action broadcasts of outdoor sports requires precise knowledge of the foreground, i.e. players present in the scene. This thesis proposes a foreground detection and segmentation- framework with focus on real-time performance for 1080p resolution. LÄS MER

  5. 19. Dynamic real-time scene voxelization and an application for large scale scenes

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

    Författare :Andreas Valter; [2015]
    Nyckelord :Voxelization; GPU; ACG; Computer Graphics; Computer games; Computer science; Media technology; Medieteknik; MT; thesis; Andreas Valter; Valter; CPU; Real time; Direct X; DX11; HLSL;

    Sammanfattning : This report describes a basic implementation of scene voxelization within the Frostbite engine created by EA Frostbite. The algorithm supports dynamic scenes by voxelizing in real-time using the Graphical Programming Unit. The voxel grid is stored inside a buffer with a binary representation using clip mapping and multiple levels of detail. LÄS MER

  7. 20. Multi-person tracking system for complex outdoor environments

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Cristina-Madalina Tanase; [2015]
    Nyckelord :video tracking; automated video surveillance; image processing.;

    Sammanfattning : The thesis represents the research in the domain of modern video tracking systems and presents the details of the implementation of such a system. Video surveillance is a high point of interest and it relies on robust systems that interconnect several critical modules: data acquisition, data processing, background modeling, foreground detection and multiple object tracking.
