Path Sampling Techniques for Efficient Light Transport Simulation
(2015-06)
Reproducing the interactions between light and matter in a physically accurate way can significantly improve the realistic appearance of synthetic images, however such effects can be very computationally expensive to ...
Quadrilateral Surface Mesh Generationfor Animation and Simulation
(Bommes, 2012-10-11)
Accurately describing the geometry of objects in a digital environment, i.e. computers, isan essential ingredient in many of nowadays applications. Often it is desired to forecastthe behavior of real phenomena which depend ...
A Frequency Analysis of Light Transport: from Theory to Implementation
(Belcour, 2012-10-30)
The simulation of complex light effects such as depth-of-field, motionblur or scattering in participating media requires a tremendous amountof computation. But the resulting pictures are often blurry. We claimthat those ...
Perceptual Display: Exceeding Display Limitations by Exploiting the Human Visual System
(Didyk, Piotr, 2012-08-20)
Existing displays have a number of limitations, which make it difficult to realistically reproduce real-world appearance; discrete pixels are used to represent images, which are refreshed only a limited number of times ...
Non-Uniform Deformable Volumetric Objects for Medical Organ Segmentation and Registration
(Erdt, 2012-06-13)
In medical imaging, large amounts of data are created during each patient examination, especially using 3-dimensional image acquisition techniques such as Computed Tomography. This data becomes more and more difficult to ...
SELF-DELAUNAY MESHES FOR SURFACES
(Dyer, 2010)
In the Euclidean plane, a Delaunay triangulation can be characterized by the requirementthat the circumcircle of each triangle be empty of vertices of all other triangles. For triangulatinga surface S in R3, the Delaunay ...
Automated methods for audio-based music analysis with applications to musicology
(Konz, 2012-11-09)
This thesis contributes to bridging the gap between music information retrieval (MIR) and musicology. We present several automated methods for music analysis, which are motivated by concrete application scenarios being of ...
Perception-Augmenting Illumination
(Solteszova, 2012-10-04)
At each stage of the visualization pipeline, the information is impeded by loss or by noise because of imprecise acquisition, storage limitations, and processing. Furthermore, it passes through the complex and not yet well ...
Continuity and Interpolation Techniques for Computer Graphics
(González García, 2013)
In Computer Graphics applications, it is a common practice to texture 3D models to applymaterial properties to them. Then, once the models are textured, they are deformedto create new poses that can be more appropriate for ...
Algorithms and Interfaces for Real-Time Deformation of 2D and 3D Shapes
(Jacobson, 2013-05-01)
This thesis investigates computer algorithms and user interfaces which assist in the process of deforming raster images, vector graphics, geometric models and animated characters in real time. Many recent works have focused ...
