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

特定の領域で OCR を実行するために、Tesseract に Rectangle オブジェクトを提供できます。 Tesseract instance = Tesseract.getInstance();

Rectangle rect = new Rectangle(coordinates.getX(), coordinates.getY(), coordinates.getWidth(), coordinates.getHeight());
String result = instance.doOCR(bufferedImage, rect);

結果は、長方形領域から認識された文字を提供します
