Granulometry
Encyclopedia
Granulometry is the measurement of the size distribution in a collection of grains.
- Granulometry (morphology)Granulometry (morphology)In mathematical morphology, granulometry is an approach to compute a size distribution of grains in binary images, using a series of morphological opening operations...
: Granulometry computation using the morphological openingOpening (morphology)In mathematical morphology, opening is the dilation of the erosion of a set A by a structuring element B:A\circ B = \oplus B, \, where \ominus and \oplus denote erosion and dilation, respectively....
operation. - Optical GranulometryOptical GranulometryOptical granulometry is the process of measuring the different grain sizes in a granular material, based on a photograph. Technology has been created to analyze a photograph and create statistics based on what the picture portrays. This information is vital in maintaining machinery in various...
: Computation of granulometries from images, and its use in mineMiningMining is the extraction of valuable minerals or other geological materials from the earth, from an ore body, vein or seam. The term also includes the removal of soil. Materials recovered by mining include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock...
