I am working on Tess4j for reading passport. Is there any function to recognise only part of passport image such as Name, Surname etc. Does Tesseract supports zonal OCR? How can I achieve this task using Tesseract? Give me some suggestions on it.

我们可以向 Tesseract 提供一个 Rectangle 对象,用于在特定区域执行 OCR。
Tesseract instance = Tesseract.getInstance();
Rectangle rect = new Rectangle(coordinates.getX(), coordinates.getY(), coordinates.getWidth(), coordinates.getHeight());
String result = instance.doOCR(bufferedImage, rect);
结果将为我们提供从矩形区域识别的字符
希望对你有帮助
