tesseract-ocrHow do I use Tesseract OCR with Maven?

Tesseract OCR is an open source Optical Character Recognition (OCR) engine developed by Google. It can be used to extract text from images. To use Tesseract OCR with Maven, you need to add the Tesseract OCR Maven dependency to your project:

<dependency>
    <groupId>net.sourceforge.tess4j</groupId>
    <artifactId>tess4j</artifactId>
    <version>3.4.8</version>
</dependency>

Once the dependency is added, you can use the Tesseract OCR API to extract text from images. For example, the following code snippet can be used to extract text from a given image:

// Create an instance of Tesseract
Tesseract tesseract = new Tesseract();

// Set the path of the language data files
tesseract.setDatapath("/path/to/tessdata");

// Extract text from the given image
String text = tesseract.doOCR(new File("/path/to/image.jpg"));

// Print the extracted text
System.out.println(text);

The output of the above code snippet would be the text extracted from the given image.
