tesseract version - Ubuntu 16.04 PPA vs compiling from tesseract-ocr github source (master-branch)

[Pushkar Pandey]

Hi All,

Could someone answer the following questions I have?

1. Is the Ubuntu 16.04 PPA the latest tesseract version right from the GitHub master branch? Is the Ubuntu PPA version in sync with the Github master branch?

2. Which traineddata (english) is installed when tesseract is installed using the Ubuntu PPA. Is it the tessdata_best or tessdata_fast or the default tessdata.

3. Which traineddata (english) produces most accurate results among the three in your experience (tessdata_best or tessdata_fast or the default tessdata).

I ask this because I see a few differences between the OCR output of Ubuntu PPA version and the compiled version of tesseract-ocr source. It could be due to different traineddata being used in the two cases. Not sure though.

Thanks,

Pushkar

tessdata_fast

Not necessarily. But  it should be pretty close, You can look at the commit number and date in the files at ppa.

It depends on your requirement and the kind of images you are using.

If you need legacy model, then you have to use tessdata.
