Gscan2pdf -- Scan, OCR Text, PDF, DjVu - Linux Mint 8

install gscan2pdf & tesseract-ocr

The gscan2pdf homepage is http://gscan2pdf.sourceforge.net/

Only two clicks are required to scan several pages and then save all or a
selection as a PDF or DjVu file, including metadata if required.

gscan2pdf can control regular or sheet-fed (ADF) scanners with SANE via
scanimage or scanadf, and can scan multiple pages at once. It presents a
thumbnail view of scanned pages, and permits simple operations such as
rotating and deleting pages.

PDF conversion is done by PDF::API2.

The resulting document may be saved as a PDF, DjVu, multipage TIFF file, or
single page image file.


The Tesseract OCR engine was originally developed at HP between 1985 and 1995.
It was open-sourced by HP and UNLV in 2005 and Google has lead further
development.

The Tesseract OCR engine was one of the top 3 engines in the 1995 UNLV
Accuracy test. Between 1995 and 2006 it had little work done on it, but it
is probably one of the most accurate open source OCR engines available. It
will read a binary, grey or color image and output text.

Closed Caption:

this was on a GE scanty PF is a scanning
program that can do more than just scan
some a course on those basics and the
main deewana coming years a
has in all CRM processes they can do
with the
tesseract as the engine so let me show
you
keys can hear might scanners not working
so
if yes is can you do the scanning what
you know it
that there's no device here issued a
screenshot of what it says
basically the have an option here doing
up pose
processing that show in a minute
but let's say you have your images
candid and
now you can imported rachel is a %um for
some images
ac3 only and you have three of them
I'll what you can do it here is actually
you know combine these images
into a PDF if you like
size go to File save
and then you have PDF
okay
and it was too big or something catchy
down
you not change the DPI ovett if you like
wouldn't really recommend them but you
can do that
but less a you see this all the pages
in our desktop has caused a
game or something in a US a PDF
I am you know her PDF have a lot of
freakin exploration vices
now that if you want to change it to
something else like
DjVu army postscript you can do that but
here they only have
is DjVu files
outsider DjVu better than PDF we have
this smaller
anne's the same quality in my opinion
survey savior's ashida size difference
to you the sky like the mp3's to
wave down
if you are compared to that you bunny
show you
so the PDF is about you see
2.1 me a place where I am for three
pages
my with this one
me that other one third of the size and
let me see how it looks like
so this is the PDF alright
Missy fit to with you no big deal
that's what it looks like and the DjVu
earlier
same seem to have a quality and I
one-third the size so
it looks you know almost the same now
but you have a bigger file
I can a book on it being you'll see that
the difference really clear
alright so just want to mention that if
you want to get a window for
UPDF crap oranges you don't like Adobe
that's another way to go
um us go on to the other ones you can do
in here
usually crops on my knees me show you
so you get a crop here you can you not
tell it to you
yet the uses to appear to select and
crop out there the part that you want
only not a big deal we can do that
all right and then click the Refresh
thing you see is back to normal
the other one party is in the game might
be useful to you
where they'll turn the white to black in
black to white here
but best doesn't really I would I
recommend you
trial an important to campaign dead in
there you like
clean up but only recommend policy on to
the OC are in process they can do
so it's like all these pages here and
when I do I'll see our
arm in you know recommend his tesseract
the the other was not that good to.see
aren't
not very good resurrect a joint use and
you have some different language
Germany range it depends what the you
know
he trying to extract from from the page
so you
if you have a good German book or
something then use Jan
okay
let's go on an do that OC on process
%uh this was mainly I would recommend is
for
I am you know books that is happy plain
text that said
not black and white tax only no color
graphics raining there that's why I
recommend and it depends on your source
to you know if you have a crappy
a scanner or you have a high DPI
or is too dark or too small then on it's
not gonna
you to come out very well side depends
on those factors to
how well you scan it in so that we have
this image ear
me zoom in on here this alright
services 200 I scanned it armed forces
to those who remain gauge
in
less complicated substances pattern love
lying goes on to these
doctor portion which is going to be
harder to recognize because
dark fired and you can see that reflects
that here
so you see her says has all those the
first word anyone is to the N
to the dark gray is the it messed up
here rain
salt it depends how well use candid
and is try some other page here so this
is a similar thing the dark parties
around this area
and you see the beginning it suffers
because %uh that
but if the N is you know recognize those
words
because is clear I love this one
this basically the same thing here may
we have a clear part here
and look at this point came out pretty
well
here there pretty much the same thing
%uh so that's that just depends on you
know how well
I use candid an hour before the lighting
was
but generally there for you also and
this is mainly for
tax i said i get a text only another way
is to
I should the other way another time but
you can actually
lead image like this and you make your
own
PDF searchable which Josh another time
