[comp.dcom.fax] fax to ascii conversion

adamg@world.std.com (Adam M Gaffin) (06/05/91)

If this one has already been beaten to death, please forgive me, but...
 
Probably nobody gets more junk fax than a newsroom, and we are getting 
tired of going through reams of expensive fax paper, so we're looking at 
replacing the machine with a computer and fax board. Our computer gurus 
have come up with some software that will turn a fax message into a PCX 
or TIFF file and another program that will convert THAT into ASCII, and 
want to write a batch file to transmit that into our main system. The 
problem is this has to be done for each individual fax, because the 
software they want to use (ReadRight is one of the programs) apparently 
can't be automated. Unfortunately, it all seems more complex than the 
average reporter or editor is willing to deal with, especially since we 
probably get 40-50 faxes (maybe more; I've never counted) a day. Does 
anybody know of any decent software for turning fax into ASCII, 
preferably automatically, or, at the least, through macros? Any help 
would be most appreciated! 
 
Thanks!

I haven't yet tried this, but it "should" work. \

Get a Macintosh with a FAX board.  Save the incoming image as TIFF.
Acquire an OCR program that accepts TIFF images.  Feed the TIFF image
into the OCR program.

Problems:
1.  FAX scanners tend to smear and add noise to characters.  Many OCR
software packages produce hilarious ASCII versions of noisy characters.

2.  The OCR recognition process is relatively SLOW.  You might need a
Mac II fx to get close to usable performance if your incoming FAX traffic
is typical newsroom level.

Why the Mac?  You should be able to run both the FAX and the OCR at the same
time.  Either using MultiFinder or a FAX-receiving Desk Accessory.

I just watched a NeXT demonstration of precisely this yesterday. An incoming
fax was displayed on the screen. The user selected the text from this 
image (in a variety of fonts,sizes) and invoked an OCR program to convert
a section of the text into ASCII, which was then passed to a standard mail.

It was all done manually, but I had the distinct impression that it
would have been possible to do this all automatically.

I should try your local NeXT computer salesman. (Hey, and it could play Bach
at the same time too!)

	It's really too bad this fax to ascii conversion is
necessary.  Since so much of the stuff sent by fax is text,
the machines should just accept calls with ascii.  If someone
is using a computer to generate the stuff she/he is then going
to fax, it's a lot more efficient to just send the ascii instead
of printing it out, scanning it, doing image compression and then
sending it thru a 9600 bps modem, which the phone company then
changes to 64 kbps, which then gets changed back to voice grade
audio by the phone company at the far end, which then drives the
receiving 9600 bps modem, which then decompresses the image and
its finally printed.  Only now, we want to take this and convert
it back to the original ascii!!!  Pretty amazing!  Fax machines
work great, but it's sure getting complicated (and expensive).
	How about if the fax standards included a "print ascii"
mode.  They'd look like the old Teletype model 33 printers that
ran Bell 103 on dial up lines.  I could call it with any modem
and dump a message to it.  Sending ascii at 9600 bps (even more
with compression) would sure me more efficient for all the
nongraphic (image, not language) faxes we send.  If we need
to send an image, the machine would accept that too.
	Other great (?) fax ideas...  How about a fax machine
that works on switched 56K or ISDN lines?  Sending images at
64 kbps would be great!  Sending ascii text at that speed would
be even better?  For compatibility, I wonder if we could use
DSP to emulate the existing 9600 bps fax modems over the 56K
circuit, if we find we're talking or listening to a conventional
fax.  It seems silly for us to go to some tremendous complexity
to stuff 9600 bps down a dial up circuit when it's immediately
converted to 64 kbps at the central office.  
	Sorry about drifting a bit from the subject.  I tend 
to do that...
