Convolutional Recurrent Neural Network
Robust Scene Text Recognition with Automatic Rectification
======================================
This software implements the Convolutional Recurrent Neural Network (CRNN) in pytorch.
Origin software could be found in
[
crnn
](
https://github.com/bgshih/crnn
)
Run demo
--------
A demo program can be found in
``src/demo.py``
. Before running the demo, download a pretrained model
from
[
Baidu Netdisk
](
https://pan.baidu.com/s/1pLbeCND
)
or
[
Dropbox
](
https://www.dropbox.com/s/dboqjk20qjkpta3/crnn.pth?dl=0
)
.
This pretrained model is converted from auther offered one by
``tool``
.
Put the downloaded model file
``crnn.pth``
into directory
``data/``
. Then launch the demo by:
python demo.py
The demo reads an example image and recognizes its text content.
Example image:
![
Example Image
](
./data/demo.png
)
Expected output:
loading pretrained model from ./data/crnn.pth
a-----v--a-i-l-a-bb-l-ee-- => available

)

Train a new model
-----------------
1.
Construct dataset following origin guide. For training with variable length, please sort the image according to the text length.
2.
``python crnn_main.py [--param val]``
. Explore
``crnn_main.py``
for details.
