Regarding space in punjabi recogniton

[Vaibhav Kumar]

Hi,

I was trying to do text recogniton using tesseract on punjabi language.

The recognition is working fine.

But there is a little issue with it.

Image containing white spaces between the words is not getting recognised i.e. words are getting fetched into text file without spaces.

Please suggest some solution for this.

Looking for a positive response from your end.

Regards

Vaibhav

Please provide a sample test image and expected ground truth text.

Which version of trained data did you use?

PFA for the image.

I used the default punjabi traineddata on which tesseract-ocr is trained by the developers.

[Shree Devi Kumar]

There are three repositories with trained data files

tessdata 

tessdata_best

tessdata_fast

Please  also share the version info and command used...

tesseract -v

tesseract -v yields

tesseract 3.04.01

 leptonica-1.73

  libgif 5.1.2 : libjpeg 8d (libjpeg-turbo 1.4.2) : libpng 1.2.54 : libtiff 4.0.6 : zlib 1.2.8 : libwebp 0.4.4 : libopenjp2 2.1.2

I used tessdata 

and PFA for output file

I used the command tesseract -l pan pun1.jpg pan

Please try with tesseract 4.0.0

It should give you better recognition

I read tesseract 4.x works on ubuntu 18 .

I am using ubuntu 16.

Isn't there any other solution ?

[Shree Devi Kumar]

Read the main wiki page.

 You can install using Alex's ppa on older versions of Ubuntu.

Make sure to uninstall the 3.04 version.
