Moving Least Squares Coordinates

Computer Graphics Forum, 2010
AbstractWe propose a new family of barycentric coordinates that have closed‐forms for arbitrary 2D polygons. These coordinates are easy to compute and have linear precision even for open polygons. Not only do these coordinates have linear precision, but we can create coordinates that reproduce polynomials of a set degree m as long as degree m ...

Boundary modeling with moving least squares

Computers & Geosciences, 2019
Abstract Modeling geological boundaries is an important step in geological modeling workflows that aim to quantify the location, volume, and uncertainty of a resource. Several well established explicit and implicit techniques can be used to identify the limits of an ore zone; however, most techniques are unable to account for uncertainty in a ...

Image demosaicking based on moving least square

Journal of Ambient Intelligence and Humanized Computing, 2020
We present a demosaicking method based on moving least square to estimate to-be-interpolated color pixels. Demosaicking is a severely ill-posed problem and we need to reconstruct two color channels for each pixel. To predict the missing color pixels using the given color pixels, we rely on a generic local approximation function using moving least ...

Provably good moving least squares

ACM Transactions on Algorithms, 2005
We analyze a moving least squares (MLS) interpolation scheme for reconstructing a surface from point cloud data. The input is a sufficiently dense set of sample points that lie near a closed surface F with approximate surface normals.

Moving Least-Squares Reconstruction of Large Models with GPUs

IEEE Transactions on Visualization and Computer Graphics, 2014
Modern laser range scanning campaigns produce extremely large point clouds, and reconstructing a triangulated surface thus requires both out-of-core techniques and significant computational power. We present a GPU-accelerated implementation of the moving least-squares (MLS) surface reconstruction technique.
