i want to extract a text from textblock or image and compare against user input text

Hello Satyavathi,

Thank you for sharing details on the scenario you need to cover.

You can use the Test Studio feature to extract text into run-time variables - you can get the value from an element in the DOM tree or from an image. 

As a next step you can insert a verification in your test, which checks the user input and data drive the ExpectedString value with the extracted variable. You can check the screenshot for reference. 

I hope this information helps you adjust the required scenario. Let me know if you need further assistance on the case. 

Regards,
