Read the text from image (captcha) by using Selenium WebDriver with Java

Question

We have a registration webpage but in last captcha is displaying and not able to read text from image.

My code

@Test
public void loginTest() throws InterruptedException {
    System.out.println("Testing");
    driver.get("https://customer.onlinelic.in/ForgotPwd.htm");

    WebElement element = driver.findElement(By.xpath("//*[@id='forgotPassword']/table/tbody/tr[5]/td[3]/img"));
    System.out.println(" get the instance ");

    String elementTest = element.getAttribute("src");
    System.out.println("Element : " + elementTest);
}

Error

A sample code you can use 

import java.awt.Image;

import java.awt.image.BufferedImage;

import java.awt.image.RenderedImage;

import java.io.File;

import java.io.IOException;

import java.net.URL;

import javax.imageio.ImageIO;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.testng.annotations.BeforeTest;

import org.testng.annotations.Test;

import com.asprise.util.ocr.OCR;

public class ExtractImage {

 WebDriver driver;

 @BeforeTest

  public void setUpDriver() {

   driver = new FirefoxDriver();

  }

 @Test

 public void start() throws IOException{

 /*Navigate to http://www.mythoughts.co.in/2013/10/extract-and-verify-text-from-image.html page

  * and get the image source attribute

  *  

  */  

 driver.get("http://www.mythoughts.co.in/2013/10/extract-and-verify-text-from-image.html");

 String imageUrl=driver.findElement(By.xpath("//*[@id='post-body-5614451749129773593']/div[1]/div[1]/div/a/img")).getAttribute("src");

 System.out.println("Image source path : \n"+ imageUrl);

 URL url = new URL(imageUrl);

 Image image = ImageIO.read(url);

 String s = new OCR().recognizeCharacters((RenderedImage) image);

 System.out.println("Text From Image : \n"+ s);

 System.out.println("Length of total text : \n"+ s.length());

 driver.quit();

 /* Use below code If you want to read image location from your hard disk   

  *   

   BufferedImage image = ImageIO.read(new File("Image location"));   

   String imageText = new OCR().recognizeCharacters((RenderedImage) image);  

   System.out.println("Text From Image : \n"+ imageText);  

   System.out.println("Length of total text : \n"+ imageText.length());   

   */
