| # Randall Open Manuscript Segmentations |
|
|
| This is a dataset of hand-annotated segmentation maps for medieval manuscripts indexed in Lilian Randall's |
| Images in the Margins of Gothic Manuscripts (1966). It contains 148 training pages and |
| 21 test pages with semantic segmentation masks that distinguish 7 classes of decorative elements. |
| Text, blank page, and other non-decorative regions pixels are grouped together into the background class. |
|
|
| ## Fields |
|
|
| - `name`, `uuid`, `pixel_values`, `labels`, `label_status`, |
| `segments_metadata`, and `segments_annotations`. |
| - `source_image_credit` gives a page-specific source credit containing the |
| holding institution, manuscript shelfmark/accession, and folio/page when one |
| is available. |

| ## Included sources and image rights |
|
|
| This is a mixed-rights dataset. The `license: other` metadata deliberately does |
| not claim one blanket license for every component. |
