Does have any openCV or OCR tesseract tutorial for extracting ?

The fastest way (maybe not the ideal) is to implement the following steps:

Use OpenCV to detect the paper sheet or the text area;
Perform any processing necessary to deskew the image (if necessary);
Save the image to disk as TIFF;
and finally, call Tesseract cmd-line application passing the TIFF image as parameter to start the text recognition process.
