Hi I'm trying to create a traineddata with a specific word list. What I have done so far is: 1.) Create specific files langdata/eng - eng.wordlist (containing my specific words) - eng.finetune.training_text (representative text containing only chars found in my words) - eng.numbers a

[tesseract-ocr] Retrain Tesseract 4.0.0 beta to recognise handwritten digits

*Hi,* *Recently I trying to retrain Tesseract 4.0 for recognising handwritten digits. I am following official page but finding it very difficult. It would be great if someone can elaborate below steps* - Prepare training text.

Re: [tesseract-ocr] Retrain Tesseract 4.0.0 beta to recognise handwritten digits

Have a look at this thread: https://groups.google.com/forum/#!topic/tesseract-ocr/be4-rjvY2tQ It's easier than it seems, you do not need per character boxes with 4.0, just one per line (that ocr-d automatically generates). If your text is already split into lines you do not have to do anything m

Re: [tesseract-ocr] Retrain Tesseract 4.0.0 beta to recognise handwritten digits

​​ Generating the training data is a completely different problem from training tesseract. If you want to recognize full words it's better to have full words (or numbers), not individual characters so that the process of splitting the words into characters is done by tesseract. Unless you just wa

Re: [tesseract-ocr] Retrain Tesseract 4.0.0 beta to recognise handwritten digits

Try creating a text corpus with only digits using various handwritten fonts that come close to your dataset from fonts.google.com. Use tesstrain.sh for rendering the images, and lstmtraining to train tesseract - you'll achieve a fair accuracy. On Tue, Jul 17, 2018 at 11:38 PM Lorenzo Bolzani wrot
