2D Image Reconstruction Using Natural Neighbour Interpolation
In this paper, we explore image reconstruction from irregularly spaced samples using natural neighbour interpolation. We sample the image irregularly using techniques based on the Laplacian or the derivative in the direction of the gradient. Local coordinates based on the Voronoi diagram are used in natural neighbour interpolation to quantify the \neighbourliness" of data sites. Then we use nat...
متن کاملSSD: Smooth Signed Distance Surface Reconstruction
We introduce a new variational formulation for the problem of reconstructing a watertight surface defined by an implicit equation, from a finite set of oriented points; a problem which has attracted a lot of attention for more than two decades. As in the Poisson Surface Reconstruction approach, discretizations of the continuous formulation reduce to the solution of sparse linear systems of equa...
متن کاملSSD-C: Smooth Signed Distance Colored Surface Reconstruction
In this chapter we address the problem of reconstructing the surface geometry, topology, and color map of a 3D scene from a finite set of colored oriented points. These data sets are nowadays obtained using a variety of techniques, including multi-view stereo reconstruction methods from multiple 2D images. We describe a novel variational method which reduces the problem to the solutions of spar...
متن کاملAn Algorithm for Centreline Extraction Using Natural Neighbour Interpolation
Data caption and conversion are two of the most costly operations of any GIS, in terms of computer time and manual work needed for spatial data acquisition. They can represent up to 80 percent of the total implementation costs. Manual digitising is a very error prone and costly operation, especially due to the lack of explicit topology in commercial GIS systems. Indeed, each map update might re...
