  2. 6. Higher-Order Regularization in Computer Vision

    Author : Johannes Ulén; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Regularization; Segmentation; Dense Stereo;

    Abstract : At the core of many computer vision models lies the minimization of an objective function consisting of a sum of functions with few arguments. The order of the objective function is defined as the highest number of arguments of any summand. READ MORE

  4. 7. Spatial vision in diverse invertebrates

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

    Abstract : 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,. READ MORE

  5. 8. Binding Three Kinds of Vision

    Author : Leo Poom; Myron Braunstein; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 9. Neurons against Noise : Neural adaptations for dim light vision in hawkmoths

    Author : Anna Stöckl; Funktionell zoologi; []
    Keywords : vision; insect; hawkmoth; motion vision; spatial and temporal summation; dim light; neural processing;

    Abstract : All animals perceive the world through their senses, which form the basis for their decisions and motor actions. However, when these all-important senses reach their limit and cease to provide reliable information, the animal’s survival is threatened. READ MORE

  7. 10. Optics for Low Vision Enabling

    Author : Jörgen Gustafsson; Certec - Rehabiliteringsteknik och Design; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Eccentric viewing; Low vision optics; Low vision rehabilitation; People with low vision; Preferred retinal; locus PRL ; Resolution; Visual acuity; Ophtalmology; Medicinsk teknik; Medical technology; Rehabilitering medicinsk och social ; rehabilitation; revalidation; kinesitherapy; Oftalmologi; Physical medicine; Contrast sensitivity; Detection; Eccentric correction; CFL ; Central visual field loss; Central scotoma; Aberrations; Astigmatism;

    Abstract : For people with central visual field loss, eccentric vision is all that they have to rely on. Even for those who learn how to correctly utilize their eccentric vision, it will never be as good as the central for two entirely different reasons: the off-axis optics of the eye can result in large refractive errors, and the low function of the peripheral retina.
