You should cut the data by yourself.Use the target_cut.py, you only need to change the data path to your own origin data.I use the dataset like ICPR MTWI 2018. Note,I use Affine changes the change the Oblique picture to rectangle.So I need the clockwise direction of target label. Use the getTxt.py to change the label's direction.

Next, use mjsynth-tfrecord.py to change your data into tfrecord.You can Find the way in [weinman/cnn_lstm_ctc_ocr/Makefile] You only need to change some paths.

I use the new word_dictionary which consists of English, Chinese and number.I only upload a old pretrain model,it works badly. If you train it for one day with your data,it will work well.And,I add some data augmentation for the model. You also can change the model to denseNet,it will work better.Do as follows in the train.py :

Import denseNet 
%features,sequence_length = model.convnet_layers( image, width, mode)
features,sequence_length = zf_mod_denseNet2.Dense_net( image, width, mode)

I only share the origin Model which is trained on ICPR MTWI 2018 (train): [model_download].The password is 2h1z. Some English data can find in [weinman]

Download models and copy it to data/model. Then,Run:

python validate.py  your picture's path
eg.python validate.py E:/1.jpg

I already upload MTWI 2018 data£¬You can download and copy to data/model/.After that ,train the model for a day,you can get your own model.[ICPR MTWI 2018 data+extra Eng-data+Eng-data].The password is diyj. When we make your data to tfrecord,You can train. I suggest you had better use your own data.

cd src
python train.py

use also can test the tfrecord's accuracy.[usage] put your data in src/data/val and do as follows:

cd src;
python test.py

Here are some results on ICPR MTWI 2018:
