       -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

       -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

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

       -hi <hocrfile>, --hocr_in=<hocrfile>
