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:

Leaf shape analysis using the multiscale Minkowski fractal dimension, a new morphometric method: a study with Passiflora (Passifloraceae)
Rodrigo de Oliveira Plotze,Maurício Falvo,Juliano Gomes Pádua,Luís Carlos Bernacci,Maria Lucia Carneiro Vieira,Giancarlo Conde Xavier Oliveira,Odemir Martinez Bruno +6 more
TL;DR: A small number of leaves per species was sufficient for establishing a characteristic pattern for each of them, which constitutes an important advantage of the method in the recognition and classification procedure.

Multiple Resolution Texture Analysis and Classification
TL;DR: Textures are classified based on the change in their properties with changing resolution, and the relation of a texture picture to its negative, and directional properties are discussed.

Characterizing the lacunarity of random and deterministic fractal sets
C. Allain,Michel Cloitre +1 more
TL;DR: The lacunarity of a set is defined from the fluctuations of the mass distribution function, which is found using an algorithm the authors call the gliding-box method, and this definition is applied to characterize the geometry of random and deterministic fractal sets.
