Wavelet-Based Multiresolution Surface Approximation from Height Fields
… of representing three-dimensional surfaces, and multiresolution analysis (MRA) is often used to obtain compact representations of dense input data, as well as to allow surface approximations at varying spatial resolution. Multiresolution approaches, particularly those moving from coarse to fine …

Applications of smoothness-increasing accuracy-conserving filtering to particle-in-cell data denoising, enhanced multiresolution analysis, and entropy-correction schemes
… procedure can be viewed within the framework of multiresolution analysis (MRA), making it a natural candidate for application in mesh adaptive DG schemes, where it provides a means of providing more accurate approximations with reduced degrees of freedom as compared to uniformly refined data. To …

Image Approximation using Triangulation
… 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 simplification operations, which try to minimize the total error of the reconstructed …
