  1. 1. Computational Methods for Computer Vision : Minimal Solvers and Convex Relaxations

    Författare :Viktor Larsson; Mathematical Imaging Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Geometric Vision; minimal solvers; Convex relaxation; Pose estimation;

    Sammanfattning : Robust fitting of geometric models is a core problem in computer vision. The most common approach is to use a hypothesize-and-test framework, such as RANSAC. In these frameworks the model is estimated from as few measurements as possible, which minimizes the risk of selecting corrupted measurements. LÄS MER

  3. 2. Aspects on Function in Age-Related Macular Degeneration

    Författare :Christina Winther; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; age-related macular degeneration; macula; macular oedema; rarebit; reading test; reading speed; self-test; smartphone application; vision test; visual acuity;

    Sammanfattning : Age-related macular degeneration (AMD) is one of the leading causes of severe visual loss among persons ≥ 60 years. AMD can be categorized in one of three stages: early, intermediate, or late. In early AMD visual symptoms are inconspicuous whereas, in the late stage, severe loss of vision is common. Late AMD has dry and wet forms. LÄS MER

  4. 3. Spatial vision in diverse invertebrates

    Författare :John Kirwan; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vision; visual ecology; invertebrates; spatial resolution; behaviour;

    Sammanfattning : Light-detection provides incomparabaly rapid information at a range of time scales and, consequently, directional photoreception is found in almost every major metazoan clade. Conversely, a much smaller cohort have evolved sophisticated high resolution vision, which facillitates complex tasks via the detection of fast or small objects,. LÄS MER

  5. 4. Binding Three Kinds of Vision

    Författare :Leo Poom; Myron Braunstein; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Attribute-invariance; binding; contours; edge linking; gestalt-laws; illusory contour; lateral interactions; neuronal mechanisms; tilt effect; vision; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : Pictorial cues, together with motion and stereoscopic depth fields, can be used for perception and constitute ‘three kinds’ of vision. Edges in images are important features and can be created in either of these attributes. LÄS MER

  7. 5. Local Features for Range and Vision-Based Robotic Automation

    Författare :Fredrik Viksten; Robert Forchheimer; Achim Lilienthal; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Local features; object pose estimation; range data; Image analysis; Bildanalys;

    Sammanfattning : Robotic automation has been a part of state-of-the-art manufacturing for many decades. Robotic manipulators are used for such tasks as welding, painting, pick and place tasks etc. LÄS MER
