File:Delaunay tessellation field estimator (overview).jpg

Overview of the Delaunay Tessellation Field Estimator (DTFE) reconstruction procedure. Given a point distribution (top left), one has to construct its corresponding Delaunay tessellation (top right), estimate the density at the position of the sampling points by taking the inverse of the area of their surrounding contiguous Voronoi cells (bottom right) and finally to assume that the density varies linearly within each Delaunay triangle, resulting in a volume-covering continuous density field (bottom left).
