LINE VORONOI DIAGRAM BASED INTERPOLATION AND APPLICATION TO DIGITAL TERRAIN MODELLING
triangulation reconstruction technology
2015/6/1
Local coordinates based on the Voronoi diagram are used in natural neighbour interpolation to quantify the “neighbourliness” of
data sites. In an earlier paper, we have extended the natural neighbour...
