NAME¶
combine_lang_model - generate starter traineddataSYNOPSIS¶
combine_lang_model --input_unicharset filename --script_dir dirname --output_dir rootdir --lang lang [--lang_is_rtl] [pass_through_recoder] [--words file --puncs file --numbers file]DESCRIPTION¶
combine_lang_model(1) generates a starter traineddata file that can be used to train an LSTM-based neural network model. It takes as input a unicharset and an optional set of wordlists. It eliminates the need to run set_unicharset_properties(1), wordlist2dawg(1), some non-existent binary to generate the recoder (unicode compressor), and finally combine_tessdata(1).OPTIONS¶
-l langThe language to use. Tesseract uses 3-character ISO 639-2
language codes. (See LANGUAGES)
--script_dir PATH
Directory name for input script unicharsets. It should
point to the location of langdata (github repo) directory. (type:string
default:)
--input_unicharset FILE
Unicharset to complete and use in encoding. It can be a
hand-created file with incomplete fields. Its basic and script properties will
be set before it is used. (type:string default:)
--lang_is_rtl BOOL
True if language being processed is written right-to-left
(eg Arabic/Hebrew). (type:bool default:false)
--pass_through_recoder BOOL
If true, the recoder is a simple pass-through of the
unicharset. Otherwise, potentially a compression of it by encoding Hangul in
Jamos, decomposing multi-unicode symbols into sequences of unicodes, and
encoding Han using the data in the radical_table_data, which must be the
content of the file: langdata/radical-stroke.txt. (type:bool
default:false)
--version_str STRING
An arbitrary version label to add to traineddata file
(type:string default:)
--words FILE
(Optional) File listing words to use for the system
dictionary (type:string default:)
--numbers FILE
(Optional) File listing number patterns (type:string
default:)
--puncs FILE
(Optional) File listing punctuation patterns. The
words/puncs/numbers lists may be all empty. If any are non-empty then puncs
must be non-empty. (type:string default:)
--output_dir PATH
Root directory for output files. Output files will be
written to <output_dir>/<lang>/<lang>.* (type:string
default:)
