mftraining \- feature training for Tesseract

.sp

mftraining \-U \fIunicharset\fR \-O \fIlang\&.unicharset\fR \fIFILE\fR\&...

.sp

mftraining takes a list of \&.tr files, from which it generates the files \fBinttemp\fR (the shape prototypes), \fBshapetable\fR, and \fBpffmtable\fR (the number of expected features for each character)\&. (A fourth file called Microfeat is also written by this program, but it is not used\&.)

.PP

\-U \fIFILE\fR

.RS 4

(Input) The unicharset generated by unicharset_extractor(1)

.RE

.PP

\-F \fIfont_properties_file\fR

.RS 4

(Input) font properties file, each line is of the following form, where each field other than the font name is 0 or 1:

.sp

.if n \{\

.RS 4

.\}

.nf

*font_name* *italic* *bold* *fixed_pitch* *serif* *fraktur*

.fi

.if n \{\

.RE

.\}

.RE

.PP

\-X \fIxheights_file\fR

.RS 4

(Input) x heights file, each line is of the following form, where xheight is calculated as the pixel x height of a character drawn at 32pt on 300 dpi\&. [ That is, if base x height + ascenders + descenders = 133, how much is x height? ]

.sp

.if n \{\

.RS 4

.\}

.nf

*font_name* *xheight*

\-D \fIdir\fR

.RS 4

Directory to write output files to\&.

.RE

\-O \fIFILE\fR

.RS 4

(Output) The output unicharset that will be given to combine_tessdata(1)

.RE

.sp

tesseract(1), cntraining(1), unicharset_extractor(1), combine_tessdata(1), shapeclustering(1), unicharset(5)
