TLDR
In this paper, X-ray microtomography (μCT) is used to evaluate changes on micromorphological and geometrical properties (porosity, number of pores, pore length, elongation, shape, connectivity and tortuosity) of a soil cultivated under no-tillage system (NTS) caused by the application of lime on the surface.About:

Assessing the long-term effects of zero-tillage on the macroporosity of Brazilian soils using X-ray Computed Tomography.
Marcelo Valadares Galdos,Luiz F. Pires,Hannah V. Cooper,Juliano Carlos Calonego,Ciro Antonio Rosolem,Sacha J. Mooney +5 more
TL;DR: The results from this study indicate that long-term adoption of ZT leads to higher macroporosity and connectivity of pores which is likely to have positive implications for nutrient cycling, root growth, soil gas fluxes and water dynamics.

X-ray microtomography analysis of representative elementary volume (REV) of soil morphological and geometrical properties
Jaqueline A.R. Borges,Luiz F. Pires,F.A.M. Cássaro,Waldir L. Roque,Richard J. Heck,Jadir Aparecido Rosa,Fabiano G. Wolf +6 more
TL;DR: In this article, 3D X-ray computed microtomography (μCT) images were used for investigating the representative elementary volume (REV) for soil properties such as soil macroporosity (MAP), number of macropores (NMAP), pore tortuosity (τ), and connectivity (Euler-Poincare characteristic, EPC) under no-tillage (NT) and conventional (CT) tillage systems.

3D analysis of the soil porous architecture under long term contrasting management systems by X-ray computed tomography
TL;DR: In this paper, the effect of three contrasting tillage systems (zero-tillage, ZT, reduced tillage, RT, conventional tilage, CT) in the soil porous system of an Oxisol was analyzed.

Lime application effects on soil aggregate properties: Use of the mean weight diameter and synchrotron-based X-ray μCT techniques
Talita R. Ferreira,Luiz F. Pires,Dorthe Wildenschild,André Maurício Brinatti,Jaqueline A.R. Borges,André Carlos Auler,Aline M.H. dos Reis +6 more
TL;DR: In this article, the effects of surface liming on the intra-aggregate porous system of soil aggregates with equivalent diameters of 2-4 and 1-2mm, from 0 to 10 (A) and 10 to 20 cm (B) soil layers were investigated.

A non-local algorithm for image denoising
TL;DR: A new measure, the method noise, is proposed, to evaluate and compare the performance of digital image denoising methods, and a new algorithm, the nonlocal means (NL-means), based on a nonlocal averaging of all pixels in the image is proposed.
