Hello Shree, I realize this post is more than two years old now, but would appreciate any help. I tried your suggestion on the same attached sample using tesseract v4 and I am unable to get the result as you have posted. I have tried all page segmentation modes, but none of them produced the result you have posted. Could you please let me know what I might be doing wrong?
