Discrete Coons patches
We investigate surfaces which interpolate given boundary curves. We show that the discrete bilinearly blended Coons patch can be defined as the solution of a linear system. With t...

Construction and smoothing of triangular Coons patches with geodesic boundary curves
Given three regular space curves r1(t), r2(t) r3(t), t [ 0, 1 ] that define a curvilinear triangle, we consider the problem of constructing a C2 triangular surface patch R(u1, u2...

Discrete texture traces: Topological representation of geometric context
Modeling representations of image patches that are quasi-invariant to spatial deformations is an important problem in computer vision. In this paper, we propose a novel concept, t...

Geometric Feature Estimators for Noisy Discrete Surfaces
Abstract. We present in this paper robust geometric feature estimators on the border of a possibly noisy discrete object. We introduce the notion of patch centered at a point of th...

Mosaicfaces: a discrete representation for face recognition
Most face recognition algorithms use a “distancebased” approach: gallery and probe images are projected into a low dimensional feature space and decisions about matching are b...
