PETROG uses a patented technique (UK2480065) to extend the usefulness of a point count, by treating the points logged as guidance to an automated classification procedure. This provides a considerable improvement on the standard determination of porosity by counting blue pixels or plagioclase from pink, K-feldspar from yellow, etc. depending on staining.
