Dataset for automated grain size characterization of rock fragments

This is the official dataset of "Automated grain size characterization and gradation evaluation of rock fragments for dam construction using close-range UAV photogrammetry," which we have decided to release ahead of our impending research paper publication. UAV images of rock fragments which we used for grain size characterization. It contains a large number of rock fragments photos that are not limited to those used in our paper.
