  1. 1. High Contrast Imaging Through Scattering Media Using Structured Illumination Fourier Filtering

    Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :David Frantz; [2017]
    Nyckelord :scattering media; Structured Illumination; optical Fourier filtering; Modulation Transfer Function; Monte Carlo simulation; Technology and Engineering;

    Sammanfattning : In imaging, obtaining high contrast is of great importance. When imaging through scattering media, optical filtering techniques are used to filter out multiple light scattering which causes loss of contrast. LÄS MER

  3. 2. Creation & Assessment of a Video Quality Ruler

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Maya Shah; [2016]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Image quality has always been a matter of great importance for anyone working with or consuming images and videos. Images and videos are, in general, for human consumption. Thus, image quality is essentially a subjective attribute of an image. LÄS MER

  4. 3. Temporal resolution efficiency and auditory stream segmentation development

    Magister-uppsats, Lunds universitet/Logopedi, foniatri och audiologi

    Författare :Marlin Johansson; [2013]
    Nyckelord :Temporal resolution; auditory stream segmentation; Listening is Spatialized Noise-Sentence test; Temporal modulation transfer function; amplitude modulation; children; maturation; development; Medicine and Health Sciences;

    Sammanfattning : Background: The ability to hear changes in a sound envelope is called temporal resolution and is assumed to have a key role in binaural speech segmentation. The development of temporal resolu-tion is not fully explored, but studies indicate that it develops into adult-like efficiency at approxi-mately 8-13 years of age, while binaural speech segmentation has an extended development up until approximately 13-16 years of age.

  5. 4. Optimization of X-ray Source for Digital Mammography -  X-ray Optics Approach

    Master-uppsats, Institutionen för medicinsk teknik; Tekniska högskolan

    Författare :Mineh Nazary; [2012]
    Nyckelord :;

    Sammanfattning : The work presents a new design of X-ray source for digital mammography imaging with the help of crystal sources and X-ray optics technology. The aim of the project was to introduce a new source for medical x ray imaging and evaluate its ability of performance. The source is build of an array of multiple micro-emitters instead of a single source. LÄS MER

  7. 5. Deconvolution algorithms of 2D Transmission Electron Microscopy images

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Ting Meng; Yating Yu; [2012]
    Nyckelord :Deconvolution; Image restoration; Wiener lter; Wiener deconvolution;

    Sammanfattning : The purpose of this thesis is to develop a mathematical approach and associated software implementation for deconvolution of two-dimensional Transmission Electron Microscope (TEM) images. The focus is on TEM images of weakly scattering amorphous biological specimens that mainly produce phase contrast. LÄS MER
