(Interesting applet) Java OCR image recognition

        Java image recognition technology uses tess4j technology.

1. Download Tess4J-3.2.1-src.zip
2. Download tesseract-ocr-setup-3.02.02.exe

        The directory structure after Tess4J-3.2.1-src.zip is decompressed is as follows:

         The project uses Ant to build, first add a sentence <javac srcdir="src" destdir="bin" /> in build.xml, otherwise it may not be able to build project. Build the project "File→New→Other" and select Java Project from Existing Ant Buildfile.

 
        Browse the build.xml file and build the project.

         The completed directory is as follows:

         Import the support jar in the lib folder into the project, and copy win32-x86 and win32-x86-64 to the bin directory.

         Install tesseract-ocr-setup-3.02.02.exe, the installation is completed as follows:

         After completing the above steps, you can write sample code.

public class TestDemo {

	@Test
	public void test() throws Exception {
		
		
		File imageFile = new File("Y:/ocr/test/d.png");
		if (imageFile.exists()){
			Tesseract1 tess = new Tesseract1 ();
			tess.setDatapath("C:/Program Files (x86)/Tesseract-OCR");//Set the Tesseract-OCR path
			tess.setLanguage("eng");
			List<String> configs = new ArrayList<>();
			configs.add("digits");//Set in the Tesseract-OCR\tessdata\configs directory
			tess.setConfigs(configs);//Add settings
			String s = tess.doOCR(imageFile);
			System.out.println("decode is "+s);
		}
	}

}
