You might want to experiment with different -psm values, we use 1 by default.
Also, which version of Tesseract? I think I got mine from (https://github.com/UB-Mannheim/tesseract/wiki), version: tesseract 3.05.00dev leptonica-1.73 libgif 4.1.6(?) : libjpeg 8d (libjpeg-turbo 1.4.2) : libpng 1.6.20 : libtiff 4.0.6 : zlib 1.2.8 : libwebp 0.4.3 : libopenjp2 2.1.0 From: Gordon Schneider [mailto:schneid...@transampiping.com] Sent: Tuesday, July 19, 2016 11:22 AM To: 'user@tika.apache.org' <user@tika.apache.org> Subject: RE: Extract Text from a TIFF image I installed tesseract on my PC. I ran tesseract on its own using the following command: tesseract.exe x:/java/PDFBox/Maxfield-1.tiff x:/java/PDFBox/Maxfield-1 The results are in the attached file. Not as clean as the results Timothy got. I am closer to where I want to get to but obviously I am a number of steps to my ideal solution. How to get the same results Timothy got?
