  1. 1. Efficient Implementation of Concurrent Data Structures on Multi-core and Many-core Architectures

    Författare :Bapi Chatterjee; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synchronization Primitives; Lock-free Binary search tree; Lock-free; Concurrent Data Structures;

    Sammanfattning : Synchronization of concurrent threads is the central problem in order to design efficient concurrent data-structures. The compute systems widely available in market are increasingly becoming heterogeneous involving multi-core Central Processing Units (CPUs) and many-core Graphics Processing Units (GPUs). LÄS MER

  4. 3. Efficient Document Image Binarization using Heterogeneous Computing and Interactive Machine Learning

    Författare :Florian Westphal; Håkan Grahn; Niklas Lavesson; Marcus Liwicki; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; image binarization; heterogeneous computing; recurrent neural networks; interactive machine learning; historical documents;

    Sammanfattning : Large collections of historical document images have been collected by companies and government institutions for decades. More recently, these collections have been made available to a larger public via the Internet. However, to make accessing them truly useful, the contained images need to be made readable and searchable. LÄS MER

  5. 4. Techniques for Fast and High-Quality 3D Reconstruction of General Scenes

    Författare :Sverker Rasmuson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; voxels; 3D reconstruction; computer vision; computer graphics; volumetric video;

    Sammanfattning : This thesis is a collection of techniques used for 3D reconstruction; the creation of 3D models from real world objects or scenes. Given the increase in accuracy, robustness and speed of modern methods and algorithms, new and exciting applications of this technology is constantly appearing. LÄS MER

  7. 5. Sparse Voxel DAGs for Shadows and for Geometry with Colors

    Författare :Dan Dolonius; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; directed acyclic graph; octree; compression; voxel; geometry; shadows; colors;

    Sammanfattning : Triangles are probably the most common format for shapes in computer graphics. Nevertheless, when high detail is desired, Sparse Voxel Octrees (SVO) and Sparse Voxel Directed Acyclic Graphs (DAG) can be considerably more memory efficient. One of the first practical use cases for DAGs was to use the structure to represent precomputed shadows. LÄS MER
