Randall Predicted Segmentations

This dataset contains 49,994 predicted semantic segmentation maps for 148 medieval manuscripts indexed in Lilian Randall's Images in the Margins of Gothic Manuscripts (1966). Each predicted segmentation map is linked to manuscript, archive, and folio/page metadata.

These segmentations were generated by a model based on a multi-class adaptation of the MapSAM model proposed in Xia et al. (2025). Further details of the model training can be found in ADD IN.

Fields

• manuscript: normalized public manuscript identifier.
• archive: holding institution or image provider.
• page: folio or page label from the manuscript inventory.
• segmentation_width and segmentation_height: prediction dimensions.
• segmentation_map: embedded RGB PNG prediction using the colors documented in id2label.json.
• source_image_credit: page-specific credit for the source image from which the prediction was derived.

The dataset does not contain source manuscript images.

Attribution and rights

source_image_credit records provenance for an omitted source image; it is not a license and does not mean attribution alone authorizes image reuse. The represented institutions have mixed image-reuse terms, including open, conditional, permission-based, and unresolved records. Generic source identifiers remain explicitly generic rather than being presented as verified shelfmarks. Users should review current source-record terms and determine whether their intended use is permitted.

The predictions are model outputs rather than human-reviewed ground truth.
