Local Analysis for 3D Reconstruction of Specular Surfaces - Part II
We analyze the problem of recovering the shape of a mirror surface. We generalize the results of [1], where the special case of planar and spherical mirror surfaces was considered,...

Tomographic Reconstruction of Piecewise Smooth Images
In computed tomography, direct inversion of the Radon transform requires more projections than are practical due to constraints in scan time and image accessibility. Therefore, it...

Smooth Adaptive Fitting of 3D Models Using Hierarchical Triangular Splines
The recent ability to measure quickly and inexpensively dense sets of points on physical objects has deeply influenced the way engineers used to represent shapes in CAD systems, ...

Invariant Geometric Representation of 3D Point Clouds for Registration and Matching
Though implicit representations of surfaces have often been used for various computer graphics tasks like modeling and morphing of objects, it has rarely been used for registratio...

Two Techniques to Improve Mesh Quality and Preserve Surface Characteristics
In this paper we present two novel techniques to improve the quality of triangle surface meshes while preserving surface characteristics as much as possible. In contrast to previo...
