Abstract
A workflow for rock sample image processing is established to determine geometrical parameters of rock texture. Individual pores and grains are identified using Hoshen-Kopelman multi-cluster labeling algorithm and watershedding technique. Separated elements are fitted with ellipses and pore/grain size distributions, aspect ratios and orientations of fitting ellipses are obtained. Such information is especially valuable in interpretation and forward modeling of dielectric responses using textural models. Rock sample images by high-resolution confocal microscopy are selected to test the workflow and results are analyzed.
