[tesseract-ocr] Re: Received error unexpected surface format -1 following tesseract training (LSTM) tutorial.

I believe I have found the issue. The TrainingTesseract 4.0 document is unclear on which directory to run the command from. Specifically, under *Building the Training Tools*, it asks you to run the following commands. make make training sudo make training-install I performed this task where

Hello, I don't know about dumping image buffers while debugging; however, there are 2 command line options and the API that might help you or point you in the right direction. https://github.com/tesseract-ocr/tesseract/wiki/Command-Line-Usage The TSV and HOCR options allow you to output the re

So I visited the pull request page of tesseract-ocr, copied the url, added a # in front of the url and concatenated it with the url of gitpot.io. This allowed me to auto install tesseract-ocr. Afterwards I ran those two commands in the link from @Lorenzo

Have you tried calling the tesseract executable from the command line yet? Can we confirm that you've successfully downloaded and compiled Tesseract? On Monday, September 16, 2019 at 5:13:20 PM UTC-4, Clint William Theron wrote: > > com'on guys, you might think this should be easy for me but it'

The question of this post is not really applicable anymore. For now I just want to do OCR with tesseract on a node.js server which I have on gitpod.io service. I said what I have done till now... ps. What questions go through your mind while reading this that I omitted to answer that's preventi

If you downloaded Tesseract's source code from GitHub (which I think you did), you will have to follow the compilation steps for Linux on this page https://github.com/tesseract-ocr/tesseract/wiki/Compiling#linux On Mon, Sep 16, 2019 at 5:48 PM Clint William Theron < theronclintwill...@gmail.com>

should I run the following command apt-get install automake ca-certificates g++ git libtool libleptonica-dev make pkg-config I just want to make sure. Up until now all I did was: 1. Register on gitpod.io 2. concatenated gitpod.io with # https://github.com/tesseract-ocr/tesseract/pulls to downl

[tesseract-ocr] Open source (BSD) MICR dataset for Tesseract v4 + evaluation app

Hello, We've open sourced (BSD 3-Clause License) our MICR dataset and *.traineddata for Tesseract v4. This was developed as an internal R&D project and never went to production as we ended using Tensorflow. Even as a PoC it's already more accurate than many commercial products. The repo conta

[tesseract-ocr] why finetune with adding few characters can work?

Hi, I know tesseract4.0 used LTSM network to train a classification task. Therefore, vector numbers in the last layer is equal to class numbers, e.g. we have 100 characters to recognize, then the vector number is 100. My question is when we add few characters for finetuning, lets say 3 charac

Hello, Thanks again for sharing your E-13B traineddata, it was helpful. We’ve managed to get good accuracy for E-13B with Tesseract but failed with CMC-7. So, we ended using TensorFlow for both fonts. I’m curious to know which level of accuracy you’ve reached. You can check our accuracy for
