tesseract-ocrHow can I use Tesseract OCR with Java Spring Boot?

Tesseract OCR can be used with Java Spring Boot to recognize text from images. To do this, the Tesseract OCR library needs to be included in the project first.

<dependency>
    <groupId>net.sourceforge.tess4j</groupId>
    <artifactId>tess4j</artifactId>
    <version>4.5.1</version>
</dependency>

Once the library is included in the project, Tesseract OCR can be used in the code. For example, the following code can be used to recognize text from an image:

ITesseract instance = new Tesseract();
instance.setDatapath("/path/to/tessdata/");

String result = instance.doOCR(new File("image.png"));
System.out.println(result);

The code above will output the recognized text from the image.

The parts of the code are:

1. ITesseract instance = new Tesseract(); - creates an instance of the Tesseract OCR library.
2. instance.setDatapath("/path/to/tessdata/"); - sets the path to the Tesseract OCR data files.
3. String result = instance.doOCR(new File("image.png")); - runs the OCR process on the image.
4. System.out.println(result); - prints the output of the OCR process.
