    $\begingroup$ @trichoplax There is a very slight consistent rotation clockwise as a scanning artifact. I've accounted for it when segmenting. There is no variation of rotation of individual characters. Initial image Charset encoding Segmented $\endgroup$ Commented May 27, 2017 at 16:44
  • $\begingroup$ Interesting indeed. just an idea- since you make own program, how is about setting different threshold by averaging, depending on which pixel row it is - say the top pixel row contributes pixels which are >95% black, second slightly more, say, all pixels which are >94% black ... and so on. $\endgroup$ Commented May 29, 2017 at 21:58
  • $\begingroup$ @Mikhail That's a good idea, but it definitely requires tuning. $\endgroup$ Commented May 30, 2017 at 3:02
