Adaptive Frame Fields for Polycube Generation and Quad Simplification
Hexahedral (hex) meshing is the problem of approximating a 3-dimensional volume with cube-like structures, and is used to discretize arbitrary volumes to solve PDEs. The structure of a hex mesh is largely guided by its singular graph. For a hex mesh to have good quality, the hexes must have …

2D and 3D surface image processing algorithms and their applications
… of solar filament disappearance detection, 3D mesh simplification, and 3D image warping in pre-surgery simulation. Filament area detection in solar images is an image segmentation problem. A thresholding and region growing combined method is proposed and applied in this application. Based on …

Image Approximation using Triangulation
… This thesis considers the use of triangular meshes for approximating intensity images. With the help of the wavelet-based analysis, triangular meshes can be efficiently constructed to approximate the image data. In this thesis, this study will focus on local image enhancement and mesh …

Real-time Visualization of Massive 3D Models on GPU Parallel Architectures
… Most existing acceleration techniques, such as mesh simplification algorithms with hierarchical data structures, suffer from the nature of sequential executions. As data complexity increases due to the fundamental advances in modeling and simulation technologies, 3D models become complex and …
