  1. 1. Analysing and Teaching the Optics of the Eye

    Uppsats för yrkesexamina på avancerad nivå, KTH/Lärande

    Författare :Moa Volny; [2023]
    Nyckelord :Visual optics; Myopia; Peripheral vision; Peer assessment; Formative feedback; Visuell optik; Myopi; Perifer syn; Kamratbedömning; Formativ återkoppling;

    Sammanfattning : Human vision is one of the most important senses, but recently near-sightedness is growing among the population. To investigate this progression, the pheripery of the eye is being studied. Therefore, new methods are developed to examine peripheral vision. LÄS MER

  3. 2. The development of a Hardware-in-the-Loop test setup for event-based vision near-space space objects.

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Rik van den Boogaard; [2023]
    Nyckelord :Camera optics; Event-based camera; HASTE; Hardware-in-the-Loop testbench; Harris corners; KLT; Asteroid; Frame-based camera; Near-space objects; Planetary exploration; Space-simulated conditions;

    Sammanfattning : The purpose of this thesis work was to develop a Hardware-in-the-Loop imaging setup that enables experimenting with an event-based and frame-based camera under simulated space conditions. The generated data sets were used to compare visual navigation algorithms in terms of an event-based and frame-based feature detection and tracking algorithm. LÄS MER

  4. 3. Venous Component Separation From a Pulse Oximeter Signal using Blind Source Separation with Ultrasound Imaging as Reference

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Björn Walter; Stefan Piiroinen; [2021]
    Nyckelord :Photoplethysmogram; PPG; Ultrasound; Blind Source Separation; PCA; SOBI; venous component; Technology and Engineering;

    Sammanfattning : Intradialytic hypotension (IDH) is a major drawback of haemodialysis and occurs in more than every fifth dialysis treatment. There is a need for real-time measurement, with an ability to detect IDH before it occurs. Photoplethysmography (PPG) may provide sufficient information about hemodynamic status to prevent IDH.

  5. 4. Physically-based Real-time Glare

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Julien Delavennat; [2021]
    Nyckelord :Glare; Flare; Rendering; Real-time; Post-processing; Visual effects; HDR; Wave optics;

    Sammanfattning : The theme of this master’s thesis is the real-time rendering of glare as seen through human eyes, as a post-processing effect applied to a first-person view in a 3D application. Several techniques already exist, and the basis for this project is a paper from 2009 titled Temporal Glare: Real-Time Dynamic Simulation of the Scattering in the Human Eye, by Ritschel et al.

  7. 5. Relativistic Visualizations

    Magister-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Andreas Ringstam; [2020]
    Nyckelord :Special relativity; Visualization; see; observe;

    Sammanfattning : Special relativity is an area of physics that is abstract and consists of concepts and effects that is hard to link to everyday experience. From a learning perspective, that is problematic as we form new knowledge by linking it to old experiences. One approach to experience a relativistic environment is through computer simulations.
