[tesseract-ocr] Re: text2image creates char boxes for 'fi' and 'fl'. Why?
How can I set a blacklist to text2image? -c tessedit_char_blacklist=fifl doesn't work for me. My problem is that text2image writes things like this: fl 133 162 159 199 5 I tried with --ligatures=true but the result is this one: fl 133 162 159 199 5 I'll continue with my research...

My earlier successes were definitely font related. Use a blacklist, or whitelist -c tessedit_char_blacklist=fifl https://groups.google.com/d/topic/tesseract-ocr/jO_4ZMMK9xw/discussion On Saturday, September 3, 2016 at 1:45:21 PM UTC-4, fuzzy7k wrote: > > It's a language thing: https://en.wikipedia.org/wiki/Typographic_ligature > > Try specifying a specific language? > > This parameter seems like a possible association (due to the description > containing glyph): > segment_penalty_dict_nonword1.25Score multiplier for glyph > fragment segmentations which do not match a dictionary word (lower is > better). > > Let me know what you find.

[tesseract-ocr] Re: text2image creates char boxes for 'fi' and 'fl'. Why?
It's a language thing: https://en.wikipedia.org/wiki/Typographic_ligature Try specifying a specific language? This parameter seems like a possible association (due to the description containing glyph): segment_penalty_dict_nonword1.25Score multiplier for glyph fragment segmentations which do not match a dictionary word (lower is better). Let me know what you find. I had this occur recently but have been chasing other issues and haven't verified a solution.
