NEBD+: Enhanced Northern European Barley Dataset for 3D complex shape analysis and classification.
This datasheet describes a new dataset for the tasks of 3D complex shape analysis and classification. The dataset consists of 697 barley grains, grouped into the following categories: six-row Bere (Bere-R6), six-row Scandinavian (Scand-R6), two-row non-Scottish British (Brit-R2), and two-row (non-Bere) Scottish (Scot-R2), all of Orkney and Western Isles provenance. We are sharing the 697 3D models in the STL format along with their corresponding spherical harmonics coefficients in JSON format, their reconstructed 3D grains using the spherical harmonics with two different references, also in STL format, a csv metadata file, and a README.md file.
