Surface shape and curvature scales

This paper presents a multiscale, curvature-based shape representation technique for general genus zero closed surfaces. The method is invariant under rotation, translation, scaling, or general isometric deformations; it is robust to noise and preserves ...

We propose a variant of shape from shading which we call shape from image warping. The idea is that the three-dimensional shape of an object is estimated by determining how much the image of the object is warped with respect to the image of a known ...

In this paper we propose a novel spherical parameterization for closed, genus-0, two-manifold, 3Dtriangular meshes. The key point of our method concerns the Gaussian curvature criterion involved, which makes it possible to detect iteratively salient ...
