[pashah72]

Hello :confused:

I have a text which is embeded inside an image. I need to read text from Image. How to to do it? Below file(File.java) reads image file but how to read text from image? I am using java?

import java.io.*;
class File {
public static void main(String args[])
{
File f1=new File("c:\\java","abc.jpg");
System.out.println("File Name:"+f1.getName());
}
}

Looking forward for an early reply.
Thanks.

If this were easy to do, all those images on registration and mail forms to prevent bots from using them wouldn't be too good, would they?

Generally speaking, it can't be done. You could try, but it will always just be guessing based on pixels and colorization and whatnot.
It certainly won't be a simple one-method solution.

So basically you need some implementation of OCR?

IME such software needs high resolution images with good color contrast to be any good.
Works great with stuff like book and newspaper scans.
Not so good with web images. Too compressed.

Get a trial version before you buy anything. :D
