 Posted: Fri Dec 30, 2011 12:04 pm Post subject: Good (scriptable) OCR engine? |
 |
|
I'm in the need to OCR subtitles from DVDs, so that I can output them and use them as .srt. Currently I'm using avidemux and it's built-in OCR, but this makes huge problems for me, since it pretty much always uses "I" instead of "l" (big i instead of small L) or the other way round. While I can fix parts of this in an automated way, it's still a big task to fix the rest by hand - even with the support of a dictionary.
So my question is, which stand-alone OCR engine is good for this task and can ideally make use of a dictionary at runtime (german and english are most important here)? It should be somewhat scriptable and ideally doesn't need (too much) training, since the fonts on DVDs seem to be pretty much standard/comparable.
Thanks.

| I'm sorry but I think no ocr engine can be accurate enough without being well-trained |

Open source? - Seems to be no one. Only proprietary. |

Well, the problem is, avidemux shows me the images of I/l and I give it my correct answer, but even from there, it still doesn't work right most of the time.

I don't care about that, it just needs to work. I'll even pay for it, as long as there's a free trial around which doesn't want my data beforehand(ie, not like this: http://www.ocr4linux.com/en:trial).

Fine Reader (not count as advertising). Here is how-to "Recognizing graphical PGS subtitles from Blu-Ray using Fine Reader" (also works with DVD, converts graphical subs to SRT). It's on russian. There must be it in english somewhere in the net (russian is my native, so I don't search for english). Good luck.
ps. If you can't understand, I can make translate for you at common steps  |

Looks like gibberish to me, but Google did the translation, so thanks. But from the pictures, this seems like Windows software and far from scriptable, so no good for me.
I'm trying cuneiform later tonight, will see if that's any good.
