Estimation of the envelope of a point set with loose boundaries

Picard Nicolas, Bar-Hen Avner. 2000. Estimation of the envelope of a point set with loose boundaries. Applied Mathematics Letters, 13 : 13-18.

Résumé : Given a point set in R2, its envelope is defined as a contour line of the density of points with a given proportion of the points excluded. Three methods are presented and compared to estimate the envelope: one is based on Voronoï tessellation, the second on a nonparametric density estimation, and the third approach is parametric. The proposed techniques are applied to detect the faster growing trees in tree growth data.
