Ocr Example Ocropus

Update: Here is Google Docs OCR output for the same image.
On an Ubuntu it takes a cc. 20 minutes to check out Ocropus and build from source and give it a try on an example image. Here are the results.




1 Down the Rabbit-Hole
Alice was beginning to get very tired of sitting by her sister on the bank,
and of having nothing to do: once or twice she had peeped into the book her
sister was reading, but it had no pictures Or cOnversations in it, 'and what is
the use of a book, ' thought Alice 'without pictures or conversation7
So She was considering in her own mind (as well as she could, for the hot
day made her feel very sleepy and stupid) , whether the pleasure of making a
daisy-chain would be worth the trouble of getting up and picking the daisies,
when suddenly a White Rabbit with pink eyes ran close by her.
There was nothing so VERY remarkable in that ; nor did Alice think it so
VERY much out of the way to hear the Rabbit say to itself, 'Oh dearl Oh
dearl I shall be latel ' (when she thought it over afterwards, it occurred to
her that she ought to have wondered at this, but at the time it all seemed
quite natural) ; but when the Rabbit actually TOOK A WATCH OUT OF
ITS WAISTCOAT- POCKET, and looked at it, and then hurried on, Alice
started to her feet , for it flashed across her mind that she had never before
seen a rabbit with either a waistcoat-pocket , or a watch to take out of it, and
burning with curiosity, she ran across the fleld after it, and fortunately was
just in time to see it pop down a large rabbit-hole under the hedge.
In another moment down went Alice after it, never once considering how
in the world she was to get out again.
The rabbit-hole went straight on like a tunnel for some way, and then
dipped suddenly down, so suddenly that Alice had not a moment to think
about stopping herself before she found herself falling down a very deep well.
Either the well was very deep , or she fell very slowly, for she had plenty
of time as she went down to look about her and to wonder what was going
to happen next . First , she tried to look down and make out what she was
coming to, but it was too dark to see anything; then she looked at the sides
of the well, and noticed that they were flled with cupboards and book-
shelves; here and there she saw maps and pictures hung upon pegs. She took
down a j ar from one of the shelves as she passed; it was labelled ' ORANGE
MARMALADE' , but to her great disappointment it was empty: she did not
like to drop the jar for fear of killing somebody, so managed to put it into
one of the cupboards as she fell past it.
'Welll ' thought Alice to herself, 'after such a fall as this, I shall think
nothing of tumbling down stairsl How brave they'll all think me at homel
Why, I wouldn't say anything about it, even if I fell off the top of the housel '
