  1. 1. Physical characterization of coarse clasts with 3D image-analysis method : development, evaluation and application

    Författare :Solomon Tafesse; Joanne Fernlund; Mark Johnson; KTH; []
    Nyckelord :3D image analysis; Particle angularity; Sieve analysis; Particle form; Gravel analysis; Repeatability; Lithological distribution;

    Sammanfattning : This thesis presents a novel three dimensional (3D) image-analysis method for characterizing the physical characteristics of coarse particles in the field, and introduces new methodology for the total analysis of glacial till samples.The novel image analysis method, called the GID method, is capable of determining the size, shape and surface texture of each individual clast analysed.
