Really poor performance with decimal numbers

[Alberto Andreotti]

Hello,

I'm having problems with the simplest image possible.

It's a screenshot from GEdit(Ubuntu's text editor), with numbers and points. This is what I get,

23.78
15
1.6
17.6
25
225
2235
0.5

Alberto

version: tesseract 4.0.0-beta.1-285-g8d3f

run from command line like this, tesseract test_image2.png  outputbase --oem 1 --psm 1

try --psm 6

Hi,

tried it with same results, also, all other cases work well.

23.78
15
1.6
1.7
1.2
1.3
1.4
1.8
1.9

The only that won't come out well is "1.5". That's pretty crazy. Any config I may provide or something?

thanks,

Alberto.

Hi,

upscale and enhance contrast, but upscale is what really matters: each letter is 20px, a dot is about three pixel, it's probably "seen" as noise.

Bye

Hello everybody,

did anybody get this "solved". I played a lot with upscaling, gamma changes, contrast etc. but I keep on getting errors, in particular missing decimal points even though the point seem to be very well and the image of good quality. Is any param change of help?
