training handwritten digits

[raymo...@gmail.com]

Hi Shree and everyone:

I just noticed that the training process of version 4.00 was updated recently, now I plan to train handwritten digits using version 4.0, 

but before training, I have two questions:

1. is it possible to fine tuning handwritten digits using eng.traineddata, since there is not a model for digits only?

2. how many samples I need to prepare, approximately?

3. Has not GPU been supported during training ?

looking forward to your reply, thanks!

1. Yes, its possible, you'd need to change the text corpus to one consisting of digits only. Also, tesseract 4 takes in a fontlist, so try using handwritten fonts for better recognition.   

2. how many samples I need to prepare, approximately?

2. A 200-250 line corpus with 200 - 300 digits per line would suffice. At least, it did for me.

3. Has not GPU been supported during training ?

3. Tesseract 4 does not support GPU acceleration as far as I know.

 

looking forward to your reply, thanks!
