java - How to recognize specific regions from image using Tess4j java

Question

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.

Answer 1

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
