Multiscaling properties of soil images

摘要

Soil structure may be defined as the spatial arrangement of soil particles, aggregates and pores. The geometry of each one of these elements and their spatial arrangement has a great influence on the transport of fluids and solutes through the soil. Soil thin sections (STS) have been widely used to characterise them and more recently computed tomography (CT) has provided an alternative for observing intact soil structure in 3D. Both types of images are grey-scale, normally with 8 bit depth.
