>I first thought I'd need img/box files pairs, but it seems it was for Tesseract 3 and is now irrelevant... Tesseract4.0.0beta.1 does not officially support LSTM training from box/tif pairs. It uses box/tif pairs generated using the synthetic training data generation pipeline using a training_text and set of fonts, for making the lstmf files that are used by lstmtraining. langdata refers to the langdata repository under tesseract-ocr github repo. The files in it have not been updated for 4.0.0 ShreeDevi ____________________________________________________________ भजन - कीर्तन - आरती @ http://bhajans.ramparivar.com On Mon, Mar 12, 2018 at 2:00 PM, ShreeDevi Kumar <shreesh...@gmail.com> wrote: > Please try tesseract 4.0.0beta.1 with languages such as > > *enm* (English, Middle (1100-1500)) > > and > > Fraktur script > > Also, look at the following project from a few years back > > http://emop.tamu.edu/outcomes/Franken-Plus > > ShreeDevi > ____________________________________________________________ > भजन - कीर्तन - आरती @ http://bhajans.ramparivar.com > > On Mon, Mar 12, 2018 at 4:32 AM, Guillaume Desforges <aceu...@gmail.com> > wrote: > >> Hi >> >> I want to try using Tesseract 4 for old manuscript languages ("The Song >> of Roland" and such). >> >> I have looked at https://github.com/tesserac >> t-ocr/tesseract/wiki/TrainingTesseract-4.00 but the steps are very >> unclear. >> >> I have an image and a text file with the line content for each line of >> manuscript text.
