An algorithm for the automatic reconstruction of triangular mesh surface model from range images is presented. The optimal piecewise linear surface approximation problem is defined as: Given a set S of points uniformly sampled from a bivariate function ƒ(x,y) on a rectangular grid of dimension W×H, find a minimum triangular mesh approximating the surface(More)
The provably NP-hard problem of finding optimal piecewise linear approximation for images is extended from 1D curve fitting to 2D surface fitting by a dual-agent algorithm. The results not only yield a storage-efficient codec for range, or intensity, images but also a surface triangulation technique to generate succinct, accurate and visually pleasant 3D(More)
