    Sammanfattning : This thesis, within the subfield of computer science known as computer vision, deals with the use of scale-space analysis in early low-level processing of visual information. The main contributions comprise the following five subjects:The formulation of a scale-space theory for discrete signals. LÄS MER

  3. 7. Mind in Motion: The utilization of noise in the cognitive process

    Författare :Robert Pallbo; Data Vetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; AI; image processing; spontaneous activity; motion detection; knowledge acquisition; homunculus; evolutionary epistemology; evolution; cognition; noise; neural networks; Psychology; Psykologi;

    Sammanfattning : The brain is not silent. Even in the absence of stimuli are the neurons activated every now and then in what is called "spontaneous" or "background activity" which provides a noisy background to the operation of the brain. This work shows how this noise can be utilized in the cognitive process. LÄS MER

  4. 8. Applications in Monocular Computer Vision using Geometry and Learning : Map Merging, 3D Reconstruction and Detection of Geometric Primitives

    Författare :David Gillsjö; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scene Completion; Deep Learning; Bayesian Neural Network; Room Layout Estimation; Line Segment Detection; Polygon Detection; Graph Neural Network; Map Merging; Structure from Motion; Minimal Solvers; Wireframe Estimation;

    Sammanfattning : As the dream of autonomous vehicles moving around in our world comes closer, the problem of robust localization and mapping is essential to solve. In this inherently structured and geometric problem we also want the agents to learn from experience in a data driven fashion. LÄS MER

  5. 9. On Prism-based Motion Blur and Locking-proof Tetrahedra

    Författare :Mads Rönnow; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; continuous collision detection; locking; GPU; parallel; real time; FEM; motion blur; prism;

    Sammanfattning : Motion blur is an important visual effect in computer graphics for both real-time, interactive, and offline applications. Current methods offer either slow and accurate solutions for offline ray tracing applications, or fast and inaccurate solutions for real-time applications. LÄS MER
