Hi everybody, my name is Ken Felon and you're listening to another episode of Hacker Public Radio.
|
|
Today I want to talk to you about a tool that I keep forgetting about and it is an optical
|
|
character recognition tool that takes in an image file and then will convert that to text.
|
|
The brilliant thing about it is it's got loads of language support so if you're scanning
|
|
English documents it works out in the box with English.
|
|
Otherwise you can install different language packs.
|
|
For example, I've been running Tesseract-L-E-N-G.
|
|
The name of the image file, JPEG and the prefix for the extension and then that's it.
|
|
It'll just happily run and look at the optical characters, the funnels and try and
|
|
determine some text from that.
|
|
As you know, I've done a series here on scanning textbooks and stuff.
|
|
At the moment I'm doing of course myself so I scanned in the book and in order to help me learn
|
|
I have used this to convert the images into text blocks of text which I then get optical character
|
|
then text-to-speech tools like eSpeak, not like eSpeak, eSpeak to read back to me and that way I hear
|
|
what I'm learning and I see what I'm reading so that's very good too.
|
|
It also allows you to change languages as I said and it also figures out very complicated
|
|
column formats so that if you have, for example, a page with three different columns in it,
|
|
it'll it's intelligent enough to know that column 1 is here and then the text was underneath that
|
|
and from column 2 and the text from column 3 goes underneath that.
|
|
So very very cool little tool and hopefully if you have needed it's quite cool
|
|
for converting stuff to text for editing.
|
|
Okay, that's what it's talk to you later and tune in tomorrow for another exciting
|
|
episode of Hercopublic Radio.
