Fractal Analysis of Donghetang Sandstones Using NMR Measurements
, 2018Routine core analysis, thin section epifluorescence and scanning electron microscopy (SEM) analyses were performed to delineate the reservoir qualities, pore systems, and pore network characteristics of the Devonian Donghetang sandstone samples.

A fractal analysis of cell images
Journal of Neuroscience Methods, 1989Methods of digital image analysis have been adapted to measure the fractal dimension of cellular profiles. The fractal dimension is suggested as a useful measure of the complexity of a contour. Three methods produce similar results when applied to constructed, near-ideal fractal figures.

MRI Image Processing Based on Fractal Analysis
Asian Pacific Journal of Cancer Prevention, 2017Background: Cancer is one of the most common causes of human mortality, with about 14 million new cases and 8.2 million deaths reported in in 2012. Early diagnosis of cancer through screening allows interventions to reduce mortality.

Fractal Analysis on Heterogeneity of Pore–Fractures in Middle–High Rank Coals with NMR
, 2016Because of the complex nature of coal reservoirs, no determined method can clearly assess their pore–fracture structure. This paper combines a fractal method with the transverse relaxation time (T2) of nuclear magnetic resonance (NMR) to study pore ...

Fractal and multifractal analysis: A review
Medical Image Analysis, 2009Over the last years, fractal and multifractal geometries were applied extensively in many medical signal (1D, 2D or 3D) analysis applications like pattern recognition, texture analysis and segmentation. Application of this geometry relies heavily on the estimation of the fractal features.
