no output for a simple test image

[Jeremy Colton]

Hi,

i have the latest tesseract-ocr:

tesseract 3.03

 leptonica-1.70

  libgif 4.1.6(?) : libjpeg 8d : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8 : webp 0.4.0

I created an image in paint with pixels 12px and 20px numbers.  See attached.

I ran tesseract a.png out digits

And I get an empty out.txt file.

This is the simplest test and it fails!  What simple config setup have I missed?

Many thanks

Jeremy

Your image is not very "linear" in the sense that a word document is and which Tesseract by default does best with. You should try another page segmentation. I tried -psm 6 and got 

l

s

Note this is not 100% accurate so you might then try increasing the resolution of your image.

New users make all the same mistakes - wrong PSM and wrong resolution - this is mentioned in the Tesseract documentation.
