Robust estimation of adaptive tensors of curvature by tensor voting

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2005
Although curvature estimation from a given mesh or regularly sampled point set is a well-studied problem, it is still challenging when the input consists of a cloud of unstructured points corrupted by misalignment error and outlier noise. Such input is ubiquitous in computer vision.

Conformai Curvature Tensors

2011
This chapter studies conformal curvature tensors of a pseudo-Riemannian metric g. These are defined in terms of the covariant derivatives of the curvature tensor of an ambient metric in normal form relative to g. Their transformation laws under conformal change are given in terms of the action of a subgroup of the conformal group O(p + 1, q + 1) on ...

Riemann Curvature Tensor

2013
Suppose we have a coordinate system \({x}^{\mu }\) in a region of an \(n\)-dimensional Riemann (or pseudo-Riemann) manifold [20]. Components of the metric tensor \(g_{\mu \nu }\) are given as functions of \({x}^{\mu }\). We want to calculate the Riemann curvature tensor \({R}^{\mu }\,_{\nu \alpha \beta }\) and related quantities (the Ricci tensor \(R_{\
