A very simple surface signal low-pass filter algorithm that applies to surfaces of arbitrary topology that is a linear time and space complexity algorithm and a very effective fair surface design technique.Expand

The main algorithms for color texture, shape and sketch query that are presented, show example query results, and discuss future directions are presented.Expand

It is shown how this unified representation can be used for object recognition, object position estimation, and segmentation of objects into meaningful subobjects, that is, the detection of 'interest regions' that are more complex than high curvature regions and, hence, more useful as features for object Recognition.Expand

The Ball-Pivoting Algorithm is applied to datasets of millions of points representing actual scans of complex 3D objects and the quality of the results obtained compare favorably with existing techniques.Expand

This article introduces a new compressed representation for complex triangulated models and simple, yet efficient, compression and decompression algorithms, and improves on Michael Deering's pioneering results by exploiting the geometric coherence of several ancestors in the vertex spanning tree.Expand

This work describes a method to estimate the tensor of curvature of a surface at the vertices of a polyhedral approximation, obtained by computing in closed form the eigenvalues and eigenvectors of certain 3/spl times/3 symmetric matrices defined by integral formulas.Expand

A novel method to estimate the image coordinates of 3D points in the projector image plane that relies on an uncalibrated camera and makes use of local homographies to reach sub-pixel precision.Expand

A new variational formulation for the problem of reconstructing a watertight surface defined by an implicit equation, from a finite set of oriented points, which allows for a number of different efficient discretizations, reduces to a finite least squares problem for all linearly parameterized families of functions, and does not require boundary conditions.Expand

The Progressive Forest Split representation is introduced, a new adaptive refinement scheme for storing and transmitting manifold triangular meshes in progressive and highly compressed form and any surface simplification algorithm based on edge collapses can be modified to convert single resolution triangular meshes to the PFS format.Expand

No algorithm for unconstrained polygon mesh denoising can beat Laplacian smoothing in simplicity and ease of implementation. In this paper we introduce a new algorithm for polygon meshes smoothing… Expand
