Many image processing methods such as corner detection, optical flow and iterative enhancement make use of image tensors. Generally, these tensors are estimated using the structure tensor. In this work we show that the gradient energy tensor can be used as an alternative to the structure tensor in several cases. We apply the gradient energy tensor to common image problem applications such as co...

The gravity gradient tensor, which has a higher resolution than gravity, is used in variety of fields, including the discovery energy resources, auxiliary navigation, and national defense building. Our team achieved significant advancements various essential technologies, such as high-resolution accelerometers, constructed China’s first self-controllable shipboard measurement system. In laborat...

one of the main goals of interpretation of gravity data is to detect location and edges of the anomalies. edge detection of gravity anomalies is carried out by different methods. terracing of the data is one of the approaches that help the interpreter to achieve appropriate results of edge detection. this goal becomes a complex task when the gravity anomalies have smooth borders due to gradual ...

Previously, the Einstein equation has been described as an of state, general relativity equilibrium state gravity, and $f({\cal R})$ gravity a non-equilibrium one. We apply Eckart's first order thermodynamics to effective dissipative fluid describing scalar-tensor gravity. Surprisingly, we obtain simple expressions for heat flux, "temperature gravity", shear bulk viscosity, entropy density, plu...

It is shown that the addition of a topological invariant (Gauss-Bonnet term) to the anti-de Sitter (AdS) gravity action in four dimensions recovers the standard regularization given by holographic renormalization procedure. This crucial step makes possible the inclusion of an odd parity invariant (Pontryagin term) whose coupling is fixed by demanding an asymptotic (anti)self-dual condition on t...
