Quantitative Analysis for the Reconstruction of Porous Media Using Multiple-Point Statistics

Geofluids, 2020
The pore structure reconstruction of the porous media is of great importance to the research of mechanisms of fluid flow in porous media. To capture the large-scale patterns in the pore space, the multiple-point statistical technique is generally adopted

On preferred point geometry in statistics [PDF]

, 2001
A brief synopsis of progress in differential geometry in statistics is followed by a note of some points of tension in the developing relationship between these disciplines. The preferred point nature of much of statistics is described and suggests the

A location-based multiple point statistics method: modelling the reservoir with non-stationary characteristics

Open Geosciences, 2017
In this paper, a location-based multiple point statistics method is developed to model a non-stationary reservoir. The proposed method characterizes the relationship between the sedimentary pattern and the deposit location using the relative central ...

Local inhomogeneous weighted summary statistics for marked point processes [PDF]

, 2022
We introduce a family of local inhomogeneous mark-weighted summary statistics, of order two and higher, for general marked point processes. Depending on how the involved weight function is specified, these summary statistics capture different kinds of ...

Super-Resolution Reconstruction of Remote Sensing Images Using Multiple-Point Statistics and Isometric Mapping

Remote Sensing, 2017
When using coarse-resolution remote sensing images, super-resolution reconstruction is widely desired, and can be realized by reproducing the intrinsic features from a set of coarse-resolution fraction data to fine-resolution remote sensing images that ...

The cumulant generating function as a novel observable to cumulate weak lensing information

The Open Journal of Astrophysics, 2023
Key non-Gaussian properties of cosmological fields can be captured by their one-point statistics, providing a complement to two-point statistical measurements from power spectra or correlation functions.
