Spatial dispersion and clustering of soil structure through lacunarity of X-ray CT images of soil macropore volumes

Lacunarity functions have been revealed as means to measure the deviation of object?s geometrical structure from transltional invariance beyond self-similarity and fractal geometry. In this work, we will explore how lacunarity quantifies ifferent patterns of dispersion and clustering of different geometrical structures of soil macropore volumes imaged by X-ray computed tomography.
