**Optical Character Recognition made seamless & accessible to anyone, powered by TensorFlow 2 & PyTorch**

## Task: recognition

https://github.com/mindee/doctr

This model does a good job if you need to do OCR on Danish documents. 

### Example usage:

```python

from doctr.io import DocumentFile
from doctr.models import ocr_predictor, from_hub

reco_arch = from_hub('diversen/doctr-torch-crnn_vgg16_bn-danish-v1')
det_arch = "db_resnet50"

model = ocr_predictor(det_arch=det_arch, reco_arch=reco_arch, pretrained=True)
image = DocumentFile.from_images(['test.jpg'])

result = model(image)
result.show()

output = result.export()
text_str = ""

for block in output["pages"][0]["blocks"]:
    block_txt = ""
    for line in block["lines"]:
        line_txt = ""
        for word in line["words"]:
            line_txt += word["value"] + " "
        block_txt += line_txt + "\n"
    text_str += block_txt + "\n"

print(text_str)
```
