| # 9 µm ink detection labels | |
| Ink labels for training Herculaneum ink-detection models at ~9 µm isotropic resolution, across four scrolls. Labels only - no CT data; surface volumes come from the [open-data server](https://vesuvius-challenge-open-data.s3.amazonaws.com/index.html). The models trained on these labels live at [scrollprize/ink_9um](https://huggingface.co/scrollprize/ink_9um). Training and inference code: villa @ merge-ink-pipelines - see ink-detection/configs/README.md | |
| ## Layout | |
| ``` | |
| ink_9um/ | |
| labels/ | |
| aligned-scrollprizeorg-21slices/ 24 segments (PHerc0139, PHerc1667, PHercParis4, PHerc0814) | |
| <segment>/ | |
| <segment>_inklabels.zarr | |
| <segment>_supervision_mask.zarr | |
| <segment>_validation_mask.zarr (3 segments only) | |
| native9-scrollprizeorg-21slices/ 5 segments (PHerc0139 w035 w039 w040 w041 w044) | |
| <segment>/ | |
| <segment>_inklabels.zarr | |
| <segment>_supervision_mask.zarr | |
| ``` | |
| ## Labels | |
| The two folders are two different sources at the same effective scale: | |
| - `aligned-scrollprizeorg-21slices`: annotations transferred onto public 2.4 µm surface volumes, then pooled 4x in XYZ to ~9.6 µm. Arrays are 21 slices deep, annotated only at Z=10; the other planes are zero. | |
| - `native9-scrollprizeorg-21slices`: annotations made directly on native 9.362 µm PHerc. 0139 volumes. Arrays are 28 slices deep, annotated only at Z=14. | |
| They stay separate because the training configs read them as two `datasets` entries, each with its own `segments_path`. Point the entries at the two folders: | |
| ```json | |
| "datasets": [ | |
| { | |
| "segments_path": "/path/to/ink_9um/labels/aligned-scrollprizeorg-21slices", | |
| ... | |
| }, | |
| { | |
| "segments_path": "/path/to/ink_9um/labels/native9-scrollprizeorg-21slices", | |
| ... | |
| } | |
| ] | |
| ``` | |
| The training loader finds `<segments_path>/<segment>/<segment>_inklabels.zarr` and friends on its own, so the layout here is exactly what a training run consumes. The three `_validation_mask.zarr` segments (pherc0139-w016, pherc0814-46527, pherc1667-w029) are the online-validation cases the released checkpoints report metrics on | |
| Annotations originate from the Vesuvius Challenge ink annotation dataset and were transferred onto the public surface volumes with the `tifxyz_label_transfer` scripts in [villa](https://github.com/ScrollPrize/villa) (`volume-cartographer/scripts/tifxyz_label_transfer`), with a per-case offset review | |
| ## Source volumes | |
| The labels annotate the public z-anisotropic 2.399 µm volumes downsampled to ~9.6 µm isotropic (level-2 XY, 4x z mean-pooling), with segments from PHerc. 0139 (9), Scroll 1667 (6), PHerc. Paris 4 (8), and PHerc. 0814 (1), plus 5 native 9.362 µm segments from PHerc. 0139. See the [model README](https://huggingface.co/scrollprize/ink_9um) for how inputs are prepared | |
