Hi,
these libs are needed to import, download .jar from the web and add to the project Drivers folder, restart Katalon Studio
import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
Thanks for your prompt reply.
These libs are available in Katalon by default. 
Please tell, what is this? – com.image.txt.GetImageText
hi,
sorry my typo, this is needed also
import com.image.txt.GetImageText
this .jar is needed to add project Drivers folder
Hi @Timo_Kuisma1 Could you please share this Jar file, or the download link. I couldn’t get this JAR file in google… 
Thanks Timo… Is there any dependency jar files required. Since my script is failing. Getting the below error. I have added the libtesseract304 but still failing.
java.lang.UnsatisfiedLinkError: Unable to load library 'libtesseract304':
