WebDec 27, 2024 · Roundness and sphericity have long been considered as measurements of the basic morphological properties of soil particles. Recent progress in optical image processing and analysis has enabled us to automate and rapidly perform Fourier analysis. WebDec 1, 1997 · Fragmentation of rocks occurs in resoonse to tectonic activity, percussive drilling, grinding and blasting. Soil fragmentation is the result of tillage and planting operations. Fractal theory, which deals with the scaling of hierarchical and irregur systems, offers new opportunities for modeling the fragmentation process.
