Hi All,
I am new to tesseract and need to process a pdf file using tesseract. I convert the pdf file into png (shw in below)and run through tesseract but the result is not perfect. How can I make this to work? Thank you very much in advance.
I am using Tesseract Open Source OCR Engine v3.04.00 with Leptonica.

Have you tried different page segmentation modes?
Execute tesseract from command prompt and take a took at -psm parameter options. Report here what works best.

I used -psm with option from 0 through 5 and only 1, 3, 4 and 5 produce output file. With option 1 and 3 produce the most readable outcome as following.
