A stupid OCR for malayalam language

pottan-ocr's Issues

How to use this for recognize Tamil language ?

How to use this for recognize Tamil language ?

Add documentation on this.

Create a public online service to quickly collect Data samples for OCR and setup automated release of trained models based on availability of new dataset

Cleanup dataset generation using augmentor python module

Add word-accuracy and character-error-rate

• Word Accuracy = correct-words/total-words
• Character Error Rate = Sum(edit-distance(prediction, truth))/sum(len(truth))

Migrate to apache singa since it has better support for devices

Apache singa seems to support both OpenCL and CUDA out of the box
https://singa.incubator.apache.org/en/index.html

* Remove dependency on system fonts.

• Fonts used for training should be part of training data
• Make it possible to render text using given ttf font file

Recognition issues

For the image given below,

output is as follows
'വികുസ്തിപ്ലീക്കൂമ്പഠ (ൃവ൭൭ന്രിക്കൂന്ന റിധ്രിത ന്ത്രജ്ജ൭ത്തിമ്രത്ഠ൬ ഉങ്കല്ലൂ'

How could you convert pytorch model to keras

@harish2704 I can not convert pytorch lstmcell to keras, Could you please provide some help?
Here is pytorch lstmcell,
self.att_lstm = nn.LSTMCell(1536,512)
h_att, c_att = self.att_lstm(att_lstm_input, (state[0][0], state[1][0]))
state[0][0], state[1][0] is the tensor(2, 512)

port to https://github.com/dmlc/tvm for running inside wide range of devices

Create a "thnet" or "pytorch2c" application which can run on any device by using less resources

Decide what all variations should be included while rendering a text.

Some options includes

• Bold / italic version of current font
• Use many different fonts
• Change offset position ( X, Y co-ordinates ), letter spacing, letter rotation
• Custom complex jitters and noise functions

### Setup integration with Kraken / Ocropy

This will tool will work as an engine without doing any sort of

• Layout analysis
• Column detection
• Output document generation

Etc.

It will simply do Imag with Line of text to Text conversion

Need more info on how to do the training?

I am trying to train for tamil fonts.

created this repo.
https://github.com/nithyadurai87/pottan-ocr-tamil

https://github.com/nithyadurai87/pottan-ocr-tamil/blob/master/config.yaml
added this file.

It seems the install step for training needs GPU, CUDA etc.
when installing them and enabling the NVDIA driver, my ubuntu got crashed.
reinstalled ubuntu.

Is there any way to train on cloud?
You used Floydhub.

Requesting you to add tutorial on how to train using floudhub.

Thanks.

### Add documentation & installation instructions
