  • Published 2001


A novel technique for the objective assessment of particle shape is presented. The tech~que uses complex Fourier shape descriptors and image analysis of SEM photographs of sand grain~ to provide an accurate quantification of particle morphology and texture. Three lower order Fourier descriptors, denoted “Signature Descriptors” provide measures of Elongation… (More)
