Image text reader
The module extracts text from image using the tesseract-OCR engine. Generally, text present in the images are blur or are of uneven sizes. The image is pre-processed for better comprehension by OCR. This module first makes bounding box for text in images and then normalizes it to 300 dpi, suitable for OCR engine to read.

Tesseract
This package contains an OCR engine - libtesseract and a command line program - tesseract.
Tesseract 4 adds a new neural net (LSTM) based OCR engine which is focused
on line recognition, but also still supports the legacy Tesseract OCR engine of
Tesseract 3 which works by recognizing character patterns. Compatibility with
Tesseract 3 is enabled by using the Legacy OCR Engine mode (--oem 0).
It also needs traineddata files which support the legacy engine, for example
those from the tessdata repository.

Building and running the software
This software is written in Java and can be built using Apache Maven. In order to build the software you have to follow these steps:
git clone https://github.com/tesseract4java/tesseract4java.gitcd tesseract4javagit submodule initgit submodule update-
mvn clean package -Pstandalone. This will include the Tesseract binaries for your platform. You can manually define the platform by providing the option-Djavacpp.platform=[PLATFORM](available platforms arewindows-x86_64,windows-x86,linux-x86_64,linux-x86, andmacosx-x86_64).
After you've run through all steps, the directory "gui/target" will contain the file
"tesseract4java-[VERSION]-[PLATFORM].jar", which you can run by double-clicking or executing
java -jar tesseract4java-[VERSION]-[PLATFORM].jar.
