2. 1. Hierarchical Variance Reduction Techniques for Monte Carlo Rendering

   Author : Petrik Clarberg; Institutionen för datavetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer graphics; Monte Carlo methods; importance sampling; hierarchical techniques; rendering;

   Abstract : Ever since the first three-dimensional computer graphics appeared half a century ago, the goal has been to model and simulate how light interacts with materials and objects to form an image. The ultimate goal is photorealistic rendering, where the created images reach a level of accuracy that makes them indistinguishable from photographs of the real world. READ MORE

4. 2. 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

5. 3. Physically Based Rendering of Synthetic Objects in Real Environments

   Author : Joel Kronander; Jonas Unger; Anders Ynnerman; Greg Ward; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis presents methods for photorealistic rendering of virtual objects so that they can be seamlessly composited into images of the real world. To generate predictable and consistent results, we study physically based methods, which simulate how light propagates in a mathematical model of the augmented scene. READ MORE

6. 4. Digital product catalogues : an evaluation of presentation and visualization techniques

   Author : Anders Follin; Byggnadsmekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photorealistic visualization; three-dimensional modeling; Advanced digital product catalogue; computer animation; integrated visualization information; relational database;

   Abstract : This licentiate thesis concerns advanced digital product catalogues, with the main focus on product presentation. A computer based digital product catalogue opens new possibilities for advanced product presentation and integration into the existing compute environment. Several new possibilities for product presentation become available. READ MORE

7. 5. Sparse representation of visual data for compression and compressed sensing

   Author : Ehsan Miandji; Jonas Unger; Anders Ynnerman; Hendrik P. A. Lensch; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The ongoing advances in computational photography have introduced a range of new imaging techniques for capturing multidimensional visual data such as light fields, BRDFs, BTFs, and more. A key challenge inherent to such imaging techniques is the large amount of high dimensional visual data that is produced, often requiring GBs, or even TBs, of storage. READ MORE
