aiuto.. Ho bisogno di un buon OCR! anche a pagamento

[leocata]

Mi serve un ocr, che funzioni bene perchè devo fare un lavoro, ovviamente anche non free! [-o<

[Blallo]

in ambito windows c'è abby fine reader, in ambito linux c'è il gratuitissimo kooka già incluso in slackware

[leocata]

tu hai esperienza sull'uso di kooka.... a me sembra che i motori ocr siano al quanto sperimentali... A me serve un OCR vero!

[Blallo]

io mi sono sempre trovato bene...male che vada usa abby fine reader con wine..è il migliore nel suo campo (in ambito win ovviamente)

[navajo]

non ho avuto mai grandi esigenze, kooka l ho trovato adatto per me.
Però ammetto, che cercando con google, ho visto che non sia propio il massimo.
Sempre attraverso google, ho visto Tesseract OCR. Non so dirti altro, se non il nome, magari provalo.
Ciao

[leocata]

ho scaricato tesseract e quando provo a scansire mi da:
leonardo@medusa:~$ tesseract out.pnm out.txt
Unable to load unicharset file /usr/share/tessdata/eng.unicharset
bohhh??? non voglio impazzire con lui io ho da lavorare... passo a windows

[Meskalamdug]

Usando google esce..

[phobos3576]

Usando google esce..


http://code.google.com/p/tesseract-ocr/wiki/ReadMe

E qui ci sono tutti i language file:

http://code.google.com/p/tesseract-ocr/downloads/list

[phobos3576]

Ostrega se funziona!

Formidabile!

E' un software sviluppato dalla HP e nella home page si afferma che si tratta di uno dei 3 migliori engine per l'OCR!
Leocata è passato troppo frettolosamente a Windows.

La procedura di installazione è la seguente:

1) Scaricare tesseract-2.03.tar.gz da http://code.google.com/p/tesseract-ocr/downloads/list
2) Scaricare i language file tesseract-2.00.eng.tar.gz e tesseract-2.00.ita.tar.gz da http://code.google.com/p/tesseract-ocr/downloads/list
2) Decomprimere tesseract-2.03.tar.gz in una directory temporanea (ad esempio, $HOME/Temp) in modo da ottenere $HOME/Temp/tesseract-2.03
3) Da un terminale, posizionarsi in quella directory ed eseguire:

Codice: Seleziona tutto

./configure
make

4) Andare in $HOME/Temp/tesseract-2.03/tessdata e cancellare tutti i file (sono vuoti) che iniziano per eng e ita
5) Decomprimere tesseract-2.00.eng.tar.gz e tesseract-2.00.ita.tar.gz in $HOME/Temp/tesseract-2.03
6) Diventare root (sudare) ed eseguire:

Codice: Seleziona tutto

make install

(il make install termina con un errore ma ciò non sembra pregiudicare l'installazione).

Per testare il programma bisogna prima convertire in formato .TIF il file da scansionare; a questo punto, basta eseguire:

Codice: Seleziona tutto

tesseract nomefile.tif file_di_output -l ita

L'ho provato con un documento scritto piuttosto in piccolo ed è riuscito a ricavare correttamente il 99% del testo!

Roba da pacchettizzare subito!

[Blallo]

l'ho pacchettizzato ma mi serve che mi mandiate un rc.inet2 standard..il mio non si avvia più correttamente e non so perchè non mi va più la connessione in ftp

[tigerwalk]

Questo è il mio rc.inet2 "standard" della current...

Su Slacky c'è anche ocropus, ma non ho idea di come funzioni. E' un Ocr usato da gnome-scan e usa come backend anche Tesseract. E' compilato staticamente con le librerie di Tesseract.
