| Recently, X-ray microtomography (?CT) has open a new way to study soil pore structures. However, ?CT data originally comes as gray scale images and the selection of segmentation method to binarized it has an important influence in the structure characterization. Three soil ?CT 3D images, corresponding to ploughed soil with different tillage tools, were used in this study. A multifractal analysis was applied to the original gray images avoiding image binarization to characterize and differentiate different soil structures. In this analysis we took into account the effect of image resolution and the subdivision method applied, Cube Counting (CC) and Gliding Cube (GC). Comparisons among the multifractal spectrums (MFS) estimated indicated that the reduction in resolution affected more in Molboard image in which the minimum scale included in the analysis was one voxel and it was almost imperceptible in the Chisel ? | |
