| mftraining - feature training for Tesseract | ||
|
|
||
| SYNOPSIS | ||
| -------- | ||
| mftraining -U 'unicharset' -O 'lang.unicharset' 'FILE'... | ||
|
|
||
| DESCRIPTION | ||
| ----------- | ||
| mftraining takes a list of .tr files, from which it generates the | ||
| files inttemp (the shape prototypes) and pffmtable (the number of | ||
| expected features for each character). (A third file called Microfeat | ||
| is also written by this program, but it is not used.) | ||
|
|
||
| OPTIONS | ||
| ------- | ||
| '-U' FILE | ||
| The unicharset generated by unicharset_extractor | ||
|
|
||
| '-O' FILE | ||
| The output unicharset that will be given to combine_tessdata. | ||

| UNICHARSET(5) | ||
| ============= | ||
|
|
||
| NAME | ||
| ---- | ||
| unicharset - character properties for use by Tesseract | ||
|
|
||
| DESCRIPTION | ||
| ----------- | ||
| Tesseract needs to have access to the character properties isalpha, | ||
| isdigit, isupper, islower, ispunctuation. This data must be encoded | ||
| in the unicharset data file. Each line of this file corresponds to | ||
| one character. The character in UTF-8 is followed by a hexadecimal | ||
| number representing a binary mask that encodes the properties. | ||
| Each bit corresponds to a property. If the bit is set to 1, it | ||
| means that the property is true. The bit ordering is (from least | ||
| significant bit to most significant bit): isalpha, islower, isupper, | ||
| isdigit, ispunctuation. | ||
|
|
||
| Each line in the unicharset file has four space-separated fields: | ||
| ...................................... | ||
| [character] [properties] [script] [id] | ||
| ...................................... | ||
|
|
||
| EXAMPLE | ||
| ------- | ||
| .............. | ||
| ; 10 Common 46 | ||
| b 3 Latin 59 | ||
| W 5 Latin 40 | ||
| 7 8 Common 66 | ||
| = 0 Common 93 | ||
| .............. | ||
|
|
||
| ";" is a punctuation character. Its properties are thus represented by the binary number | ||
| 10000 (10 in hexadecimal). | ||
|
|
||
| "b" is an alphabetic character and a lower case character. Its properties are thus | ||
| represented by the binary number 00011 (3 in hexadecimal). | ||
|
|
||
| "W" is an alphabetic character and an upper case character. Its properties are thus | ||
| represented by the binary number 00101 (5 in hexadecimal). | ||
|
|
||
| "7" is just a digit. Its properties are thus represented by the binary number 01000 | ||
| (8 in hexadecimal). | ||
|
|
||
| "=" is not punctuation nor a digit nor an alphabetic character. Its properties are | ||
| thus represented by the binary number 00000 (0 in hexadecimal). | ||
|
|
||
| Japanese or Chinese alphabetic character properties are represented by the binary number | ||
| 00001 (1 in hexadecimal): they are alphabetic, but neither upper nor lower case. | ||
|
|
||
| The last two columns represent the type of script (Latin, Common, Greek, Cyrillic, Han, | ||
| null) and id code of the character. | ||
|
|
||
| HISTORY | ||
| ------- | ||
| The unicharset format first appeared with Tesseract 2.00, which was the first version | ||
| to support languages other than English. The unicharset file contained only the first | ||
| two fields, and the "ispunctuation" property was absent (punctuation was regarded as | ||
| "0", as "=" is in the above example. | ||
|
