# Bodnár-Huawei Syn10k
A **mirror** of the `syn10k_plus_huawei` barcode dataset from the Szeged group
(Bodnár, Grósz, Tóth), repackaged as parquet with each image joined to its
ground-truth mask in the same row.
Released under **CC BY 4.0**, so this mirror is permitted with attribution.
## Configs
| config | rows | content | with mask |
|---|---:|---|---:|
| `warp2014` | 10,000 | synthetic warped barcode images | 10,000 |
| `huawei` | 98 | real photographs | 98 |
**Every image has its mask** — the pairing was verified by stem, and zero images
in either config are missing one.
## Fields
| field | notes |
|---|---|
| `image` | the picture (JPEG) |
| `mask` | the ground-truth mask (PNG) |
| `file_name`, `stem` | original filename and its stem |
| `subset` | `warp2014` or `huawei` |
| `has_mask` | always true in this build; kept so the schema stays honest if a future revision has gaps |
## Two notes on how to read this
**The split name is a container, not a protocol.** Both configs expose a single
split called `train` because HuggingFace requires a split name — it does **not**
encode the authors' intended train/test partition. `warp2014` is synthetic and
`huawei` is real photographs, which is the natural synthetic-train / real-test
arrangement, but this mirror does not assert that the authors used it that way.
Consult the source publication before reporting numbers as theirs.
**This is a barcode dataset, not a QR-only one.** It is included in a QR
collection because it is standard in the barcode-localisation literature and is
one of the few sets shipping pixel masks. Check the masks for what you need
rather than assuming every symbol is a QR code.
## Usage
```python
from datasets import load_dataset
syn = load_dataset("devmandan/syn10k-huawei-barcodes", "warp2014", split="train")
real = load_dataset("devmandan/syn10k-huawei-barcodes", "huawei", split="train")
syn[0]["image"], syn[0]["mask"] # PIL images, aligned
```
