OPTIONS

       -v <int>, --verbosity=<int>
              Set  verbosity level to <int>.  Possible values are 0 (default): silent operation; 1:  information
              on progress; >2: segmentation info is written to PNG files with prefix debug_.

       -h, --help
              Display help and exit.

       --version
              Print version and exit.

              Do a skew correction (recommended).

       -mf <ws>, --median_filter=<ws>
              Smooth the input image with a median filter with window size <ws>.  Default is <ws>=0, which means
              no smoothing

       -ds <s>, --despeckle=<s>
              Remove all speckle with size <= <s>.  Default is <s> = 0, which means no despeckling.

       -f, --filter
              Filter out very large (images) and very small components (noise).

       -a, --automatic-group
              Autogroup glyphs with classifier.

       -x <file>, --xmlfile=<file>
              Read training data from <file>.

       -o <xml>, --output=<xml>
              Write recognized text to file <xml> (otherwise it is written to stdout).

       -od <dir>, --output_directory=<dir>
              Writes for each input image <img> the recognized text to <dir>/<img>.txt.  Note that  this  option
              cannot be used in combination with -o (--outfile).

       -c <csv>, --extra_chars_csvfile=<csv>
              Read  additional  class  name  conversions from file <csv>.  <csv> must contain one conversion per
              line.

       -R <rules>, --heuristic_rules=<rules>
              Apply heuristic rules <rules> for disambiguation of some chars.  <rules> can be roman (default) or
              none (for no rules).

       -D, --dictionary-correction
              Correct words using a dictionary (requires aspell or ispell).

       -L <lang>, --dictionary-language=<lang>
              Use <lang> as language for aspell (when option -D is set).

       -e <int>, --edit-distance=<int>
              Correct words only when edit distance not more than <int>.

       -ho, --hocr_out
              Writes output as hocr file (only works with the -o option).

       -hi <hocrfile>, --hocr_in=<hocrfile>
              Uses an hocr input file for textline segmentation.

                                                                                                   OCR4GAMERA(1)
