Fractal signature and lacunarity in the measurement of the texture of trabecular bone in clinical CT images
TLDR
The fractal signatures of small regions of interest (32x32 pixels), computed in the frequency domain after corrections for imaging system noise and MTF, were able to characterize the texture of vertebral trabecular bone in CT images.About:

Algorithms for random fractals
TL;DR: Fractals have been used to simulate many natural phenomena in the past 200 years and they are easy to generate on computers as discussed by the authors, and the complexity of a fractal when measured in terms of the length of the shortest computer program that can generate it is very small.

An efficient approach to estimate fractal dimension of textural images
TL;DR: A new method is proposed to estimate fractal dimension in a two-dimensional (2D) image which can readily be extended to a 3D image as well.

Fractal approach to two-dimensional and three-dimensional surface roughness
J.J. Gagnepain,C. Roques-Carmes +1 more
TL;DR: In this paper, the authors show that a fractal number D can be associated with any profile or cartography, by processing a z ( x ) profile as would be done with a random motion x ( t ).

Measurement and significance of three-dimensional architecture to the mechanical integrity of trabecular bone
TL;DR: It is hypothesized that the relationship between bone volume fraction and connectivity may be substantially altered under conditions associated with aging, fragility, or metabolic bone disease, consistent with the histologic, evidence of reduced connectivity in osteopenic patients.
