| # form-field-v1-benchmark |
|
|
| The evaluation set behind the **`form-field-v1`** form-field detectors and the |
| [leaderboard](https://huggingface.co/spaces/nutrientdocs/form-field-v1-leaderboard) — **5,914 form pages** with |
| **126,938 annotated fields** (`Text`, `Choice` = checkbox/radio, `Signature`), across three variants: |
|
|
| | variant | images | fields | notes | |
| |---|---|---|---| |
| | `empty` | 2,334 | 49,171 | blank forms | |
| | `filled` | 1,826 | 39,797 | digitally-typed values | |
| | `handwritten` | 1,754 | 37,970 | handwritten (ink) values | |
|
|
| A Nutrient dataset, released under **CC-BY-4.0**. |

|
|
| ## Columns |
| - `image` — the rendered page (RGB). |
| - `page_id` — stable id; ends in `_empty` / `_filled` / `_handwritten`. |
| - `variant` — `empty` | `filled` | `handwritten`. |
| - `width`, `height` — page pixel size. |
| - `fields` — list of `{ "box": [x, y, w, h], "category": "Text"|"ChoiceButton"|"Signature" }` (page pixels). |
| - `source`, `license_class` — provenance tags. |
|
|
| ## Scoring |
|
|
| Detectors are scored with **COCO mAP50-95** (pycocotools, `maxDets [1,100,1000]`), reported overall and per |
| variant. |
|
|
| ```python |
| # pip install datasets pycocotools |
| python score_detector.py your_predictions.json |
| # predictions: [{"image_id": page_id, "category_id": 1|2|3, "score": s, "bbox": [x,y,w,h]}] |
| ``` |
|
|
| Reference numbers (mAP50-95) on this set — the `form-field-v1` family: medium **0.529 / 0.783 / 0.764**, |
| small **0.456 / 0.716 / 0.680**, nano **0.353 / 0.560 / 0.526** (empty / filled / handwritten). |
