Abstract:
Augmented Reality (AR) involves adding virtual content into real scenes. Scenes are viewed using a Head-Mounted Display or other display type. In order to place content into the user's view of a scene, the user's position and orientation relative to the scene, commonly referred to as their pose, must be determined accurately. This allows the objects to be placed in the correct positions and to remain there when the user moves or the scene changes. It is achieved by tracking the user in relation to their environment using a variety of technology. One technology which has proven to provide accur

Abstract:
In the visual perception of depth in computer graphics, people rely on a number of cues, including depth of field, relative size of objects in perspective, and shadows. This work focuses on shadows in Augmented Reality. An experiment was performed in order to measure the effects of having virtual objects cast shadows on real objects. Users performed the task of placing a virtual object on a physical table, in an Augmented Reality environment displayed on a mobile device. The virtual object was either a cube or a sphere. The effects of having shadows enabled was measured by time to task complet

Abstract:
<p>Ambient Occlusion är en teknik för ambient ljussättning i digitala tredimensionella scener. Sådana scener ljussätts vanligtvis med en konstant mängd ambient ljus på samtliga ytor oberoende av ytornas vinkel och position gentemot olika ljuskällor i scenen. Detta ger ett platt och kalt intryck och utan vidare ljussättningstekniker är det ytterst svårt att urskönja detaljer i scenen. Ambient Occlusion åthjälper detta genom att reducera mängden ambient ljus i vissa delar av scenen. Ambient ljus är en enkel approximation av det reflekterade diffusa ljuset som antas nå nästan överallt i scenen. G

Abstract:
Målet med denna studie är att utvärdera möjligheten att göra färgkorrigering i realtid. Denna färgkorrigering ska hjälpa färgblinda att lättare urskilja mellan olika färger. Ett problem med färgkorrigering är att det kan vara för långsamt för realtid. En prototyp där existerande algoritmer har implementerats på GPU istället för CPU tas fram, detta för att testa hypotesen att färgkorrigering tar mindre prestanda ifall den implementeras på GPU. Prestandaresultaten visar att det är lämpligt att göra färgkorrigering med hjälp av shaderprogrammering på GPU istället för CPU. Ett fortsatt arbete utif

Abstract:
The thesis deals with an image processing problem called image matting. The problem involves detection of a foreground and background in an image with minimal user interaction using trimaps. Foreground detection is used in image composition. The goal of the thesis is to apply already known algorithms, in this case A Global sampling matting, in an Android application. The most important result is an intuitive application that can be used for making creative viral photos. Agile methodology is applied throughout the whole application development cycle. From the very beginning, the application is

Abstract:
Unlike many Black-specific disciplines in the academy (Black psychology, Black history, etc), Black philosophy never completely forged a unique conceptual framework separate from American and Continental intellectual traditions. Instead the field has continued to define its validity by the extent that Black authors extend the thought of white philosophers towards race. This epistemic convergence, or the extent to which Black theory converges with established white philosophical traditions, and hence white racial sensibilities, continues to misguide many of the current philosophical systems of

Abstract:
L'objectif principale de la Réalité Mixte (RM) est de donner aux utilisateurs l'illusion que les objets virtuels et réels coexistent indistinctement dans le même espace. Une illusion efficace nécessite un recalage précis entre les deux mondes. Ce recalage doit être cohérent du point de vue géométrique et photométrique. Dans cette thèse, nous proposons de nouvelles méthodes de recalage photométrique pour estimer l'illumination et la réflectance de scènes réelles. Plus précisément, nous proposons des approches en nous attaquant à trois grands défis : (1) utilisation d'une seule caméra RGB-D. (2)

Detta arbete har undersökt hur mycket en volymetrisk eldeffekt med tillhörande fysiksimulering kan optimeras medan effekten samtidigt presterar tillfredställande. I bakgrunden ges en sammanfattning om eldteknikens historia. De begrepp som krävs för att förstå arbetet som helhet redogörs. I bakgrunden presenteras även den forskning som motiverar utförandet av arbetet. Bakgrunden följs av problemformuleringen med tillhörande metodbeskrivning. Problemformuleringen förklarar att optimering av en eldeffekt skall undersökas och då  eld är en mycket använd effekt. Metodbeskrivningen behandlar utföran
