Re: [tesseract-ocr] Fine tuning existing model

I think I found the problem. Running directly the new Makefile I had this error: make: *** No rule to make target 'data/train/alexis_ruhe01_1852_0018_022.box', needed by 'data/all-boxes'. Stop. The problem was a "-gt.txt" rather than a ".gt.txt" as in my train files. Now I can run your script dir

You can also use - import java.awt.Rectangle; public String ocrText(File file, String lang, ImageGeometry geometry) { String resultText = null; Tesseract instance = getTesseractInstance("TesseractEnvPath", "eng"); // define an equal or smaller region of interest on the image. Follow: // x-scale, y

Re: [tesseract-ocr] How to improve quality?

Re: [tesseract-ocr] Fine tuning existing model

You should be able to use the new makefile after you make changes for all the directory locations to match your setup. Change the language from frk to eng, though the sample training text seems to be non-english. In which case it is better for you to use the appropriate language traineddata eg. te

Re: [tesseract-ocr] Fine tuning existing model

Hi Shree, thanks for your answer. I tried the script setting: TESSDATA=extracted # here I have the eng.lstm and eng.trainedata LANGDATA=langdata-master # all langdata downladed by OCR-D MODEL_NAME = eng CONTINUE_FROM = eng First I run the old Makefile to create the boxes.

I modified the makefile for ocrd-train to do fine-tuning. It is pasted below: export SHELL := /bin/bash LOCAL := $(PWD)/usr PATH := $(LOCAL)/bin:$(PATH) HOME := /home/ubuntu TESSDATA = $(HOME)/tessdata_best LANGDATA = $(HOME)/langdata # Name of the model to be built MODEL_NAME = frk # Name of
