Help Improving OCR of a document

[adrianlfns]

Hello,

I'm using your wrapper of tesseract OCR in order to extract text from a PDF. I uploaded here a sample of the PDF that I'm attempting to perform OCR. I also uploaded the trained data that I'm using. If you attempt to perform OCR to that Image, you will see a really bad quality text. Is there anything I could do to improve the OCR output??

thank you in advance

The example appears to be very low resolution scan. Tesseract doesn't perform well in these cases the recommended resolution is approx 300dpi. Good luck
