This is a repository containing my experiments related to OCR technology.
Tesseract is an open source text recognition (OCR) Engine, available under the Apache 2.0 license. It can be used directly, or (for programmers) using an API to extract printed text from images. It supports a wide variety of languages.
Tesseract doesn't have a built-in GUI, but there are several available from the 3rdParty page.
There are two parts to install, the engine itself, and the python libraries required for bot or web API service if you intend to deploy that.
Tesseract is available directly from many Linux distributions. The package is generally called 'tesseract' or 'tesseract-ocr' - search your distribution's repositories to find it. Thus you can install Tesseract 4.x and its developer tools on Ubuntu 18.x bionic by simply running:
sudo apt install tesseract-ocr
sudo apt install libtesseract-dev
Note for Ubuntu users: In case apt is unable to find the package try adding universe entry to the sources.list file as shown below.
sudo vi /etc/apt/sources.list
Copy the first line "deb http://archive.ubuntu.com/ubuntu bionic main" and paste it as shown below on the next line.
If you are using a different release of ubuntu, then replace bionic with the respective release name.
deb http://archive.ubuntu.com/ubuntu bionic universe
git clone --depth=1 https://github.com/lulzx/ocr.git && cd ocr
pip3 install -r requirements.txt
python3 bot.py <your-token-here>
python3 api.py
That's all.
Firstly, Try to figure out on your own using web search engine which you prefer. But, if you still can't find what you need, please ask me on Telegram, @Lulzx
