I have used tess4j to extract text from image but not getting correct result
I have used tess4j but not getting correct result.
below is my code.
public static String crackImage(String filePath) {
BufferedImage img = null;
try {
img = ImageIO.read(new File(filePath));
} catch (IOException e) {
}
ITesseract instance = new Tesseract();
instance.setLanguage("eng");
// instance.setPageSegMode((3));
img= ImageHelper.convertImageToGrayscale(img);
instance.setDatapath("C:\tessdata");
try {
String result = instance.doOCR(img);
return result;
} catch (TesseractException e) {
System.err.println(e.getMessage());
return "Error while reading image";
}
}
I attached sample image.
MY output is:
arm m manner: a; man
mfl/Vemmnh 1951 mm 8221 11m 3521|||IIIIIIIIHIIIIIHIIIH

here is the best practice,
you need to do image processing prefer to use (OpenCV) before running that tess4j command.

or you can choose Google Ml KIT
