+# dieCamera — per-die crops
+
+One cropped image per physical die, labelled with its **type** and **face value**. This is
+the deliberately-simple training set for dieCamera's offline value reader — the app that
+watches a dice tray and posts the roll into a virtual tabletop
+([source](https://github.com/eschatus/diecamera)).
+
+For the full frames these crops were cut from (and the multi-die detector-training data), see
+the companion repo **[G-G-Games/diecamera-frames](https://huggingface.co/datasets/G-G-Games/diecamera-frames)**.
+
+## Schema
+
+Standard 🤗 `imagefolder` layout — `load_dataset("G-G-Games/diecamera-crops")` needs no config.
+
+```
+data/<file>.jpg        one die, cropped to its bounding box + a small margin
+data/metadata.jsonl    one row per crop
+```
+
+| column      | type   | meaning                                                                  |
+| ----------- | ------ | ------------------------------------------------------------------------ |
+| `file_name` | string | the crop image                                                           |
+| `source`    | string | `rig` (our webcam) or `roboflow:<fork>` (a third-party image, see below) |
+| `type`      | string | die type — `d4`, `d6`, `d8`, `d10`, `d12`, `d20`                         |
+| `value`     | int    | the up-face value read (d10 may be 0)                                    |
+| `date`      | string | capture date (`rig`), or publish date when the source has none           |
+
+Every die here has a **trusted** face value: rig dice are human-confirmed or placed to a
+prompt; roboflow dice are the ones a human reviewed and confirmed by hand.
+
+## Licence — read this before commercial use
+
+This dataset is **mixed-licence**, and the `source` column tells you which applies per row:
+
+| `source`          | licence                                                                          |
+| ----------------- | -------------------------------------------------------------------------------- |
+| `rig`             | **CC BY-NC 4.0 © G-G-Games** — free personal use; commercial needs a licence     |
+| `roboflow:<fork>` | **CC BY 4.0 © the fork's original author** (commercial OK, attribution required) |
+
+The **labels** on every row are G-G-Games' own work (CC BY-NC 4.0). Full terms:

+datasets, used with modifications (cropped; our own top-face type/value labels added):
