    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mortality; Health Equity; Adverse Childhood Experiences; Child Welfare; Adult Survivors of Child Adverse Events; Life Course Perspective; Birth cohort; Longitudinal Studies; Public Health Sciences; folkhälsovetenskap;

    Abstract : Taking a life course approach can help us to understand health inequalities. This thesis illustrates that socially-patterned childhood experiences might play a critical role for inequalities in mortality. The association between childhood adversity and premature mortality is investigated in the context of a 1953 Stockholm birth cohort. READ MORE

  4. 2. Shape from shading, colour constancy, and deutan colour vision deficiencies

    Author : Torbjörn Jakobsson; Karl-Arne Gustafsson; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; 3-D perception; ambiguous figures; attached shadows; cast shadows; colour constancy; colour vision deficiency; deuteranomaly; deuteranopia; shape- from-shading;

    Abstract : Four studies including ten experiments adresses interrelations between some major and classical issues in visual perception: 3-D perception, colour constancy, colour perception and colour vision deficiencies. The main experimental paradigm to investigate the issues is within that of simulated shape from shading. READ MORE

  5. 3. Algorithmic Improvements for Stochastic Rasterization & Depth Buffering

    Author : Magnus Andersson; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The field of computer graphics refers to the use of computers to generate realistic-looking images from virtual scenes. Graphics processing units use an algorithm known as rasterization to compute images of scenes viewed from a virtual camera. READ MORE

  6. 4. Efficient Methods for Volumetric Illumination

    Author : Frida Gyllensvärd; Anders Ynnerman; Anders Persson; Markus Hadwiger; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Modern imaging modalities can generate three-dimensional datasets with a very high detail level. To transfer all the information to the user in an efficient way there is a need for three-dimensional visualization. READ MORE

  7. 5. Incident Light Fields

    Author : Jonas Unger; Anders Ynnerman; Reiner Lenz; Alan Chalmers; Linköpings universitet; []
    Keywords : Computer Graphics; Image Based Lighting; Photorealistic Rendering; Light Fields; High Dynamic Range Imaging; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Image based lighting, (IBL), is a computer graphics technique for creating photorealistic renderings of synthetic objects such that they can be placed into real world scenes. IBL has been widely recognized and is today used in commercial production pipelines. However, the current techniques only use illumination captured at a single point in space. READ MORE
