[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.

Hi, I am also trying to train Tesseract 4.0 for hand written digits, I want to know what is the *best way to create pairs of [*.tif, *.gt.txt] with binarized chars and TTF's from two fonts (1869 text lines in total) . Are you using any specific tool to generate *.tif and *.gt.txt files. * *I h

Re: [tesseract-ocr] Easiest way to make a train data to recognize Handwritten Mathmatical Expression.

As per suggestions on group , I am planning to use MNIST model for handwritten . I do not have trained data, will post if work on it. On Wed, Jul 18, 2018 at 7:09 PM, Hamza Rajput wrote: > If some trained data about this application is already developed instead > of equ.traineddata, then please
