1. Tess4j

Which didn't worked so I move to apache tika.

In apacke tika , I tried with both ImageParser and JpegParser . It is giving file info but not providing text in my image file.

Answer 1

You can also run tika from the command line. Run it on just the images you want to perform OCR on:

java -jar ./tika-app/target/tika-app-1.13-SNAPSHOT.jar -t ~/Desktop/tess.png

Tika uses tesseract internally to perform OCR. So you should have that installed and on your PATH.

Answer 2

For Image processing Tessaract is the best api, which provides some methods along with java, try it once. You can find more details here
