  1. 1. Capillary Blood Flow Measurement based on Nail-fold Microscopic Images using Feature Based Velocity Estimation

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

    Författare :Yue Wang; [2019]
    Nyckelord :Nail-fold capillary; Medical image processing; Feature matching; Dual-Window matching; Optic-Flow; Nail-fold capillary; Medicinsk bildbehandling; Feature-matchning; Dual-Window-matchning; Optic-Flow;

    Sammanfattning : Microscopic video images of microcirculation have been used in clinical diagnosis for years, and theparameters obtained from images reveal most physiological activities and body organizations.Particularly, the blood flow speed is one of important indexes, which reflects the state ofmicrocirculation and make significant marks in diagnosis.

  3. 2. Dorsal visual cues in German wasp navigation

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Denis Vaduva; [2015]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : The German wasp Vespula germanica is found in the Palaeartic region of the globe. Outside this area, it is highly invasive species. It has an omnivorous diet and is able to hunt other insects and scavenge for food from both natural and anthropogenic sources. LÄS MER

  4. 3. Biomimetic trajectory tracking by means of event-based control

    Uppsats för yrkesexamina på avancerad nivå, KTH/Reglerteknik

    Författare :Lorris Dola; [2014]
    Nyckelord :;

    Sammanfattning : Flying insects are able to accomplish unprecedented flight by regulating their optic flow which is the velocty to which the environment scrolls in front of their eyes. This approach can be correlated to an event-based control where an event is generated according to the change of the environment. LÄS MER

  5. 4. FlyTracker: Design and Implementation of an Interactive Motion Tracking System

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

    Författare :Kristian Johansson; [2014]
    Nyckelord :;

    Sammanfattning : At the department of neuroscience at Uppsala University one of the research groups are working with motion vision. Motion vision is how seeing animal species process moving objects in their visual fields and how they experience self motion by generating an optic flow. LÄS MER

  7. 5. Exploring a Visual Flow Display to Enhance Spatial Orientation during Flight

    Kandidat-uppsats, Institutionen för datavetenskap

    Författare :Kristian Helde; [2002]
    Nyckelord :spatial disorientation; focal ambient visual system; optic flow; postural instability;

    Sammanfattning : The problem of spatial disorientation during flight of aircraft is briefly described, as are definitions of the phenomenon. Traditional countermeasure efforts that are often directed towards changes in the central visual field are reconsidered in favour of presentation of information in the peripheral visual field. LÄS MER
