I must correct myself there, passing it an image is already supported :)

You can try lowering your fuzz from 0.3 to 0.2, I didn't make any
experience so far how the plugin reacts to text in different
languages, so this might produce false positives.

In version 2.3b, this is not possible yet with a tool, unfortunately.
But the database is only a textfile, so you can simply search the hash
there and delete the line. Version 3.4.1 brings a tool that removes a
given hash from the database, but I am still improving it a bit, so
one can also pass it an image file to look for.

Version 2.3b
1) Here is the ouptut of the scanner (gocr -i) :
_____
date Informations
9- 11-lO06 1O_30 Le __ek-end du 3-4r'11, les adresses de cou
r_er jlectron_que des jtud_ants non
ri_nscmts j _UCL ont jtj ddsact_vjes. La ra_son est pÄrement
adm_n_strat_ve et I_je j
Ia caNe j puce. Pour permeNre j ces jtud_ants de rjcupdrer leurs
messaqes, nous
avons fa_t en soNe qu'_Is pu_ssent encore accjder j leur boîte aux
leNres jusqu'au

ANent_on, la consuttat_on se fera av_ un cI_ent de messager_e !
Thunderb_rd. Eudora,
Outlook.. .7 ou v_a le _IebMa_I ma_s plus v_a le poNa_I .
We get almost the same result with gocr -l 180 -d 2 -i
And FuzzyOCr says :
13 FUZZY_OCR BODY: Mail contains an image with common
spam text inside
Words found:
"wexe" in 3 lines
"alert" in 2 lines
"alert" in 2 lines
"investor" in 1 lines
"trade" in 3 lines
(11 word occurrences found)
But I don't find any of these words in th text above !
2) How remove an image which as been stored by mistake in the hash
database ?
Thanks

The current URL for FuzzyOcr is http://fuzzyocr.own-hero.net/
The page (wiki) is still quite under construction, but you'll find
installation instructions inside the tarball (you can try version
3.4.1 if you want, it performs better than the stable version 2.3b,
just isnt tested as long yet..). Installation itself is not hard if
you have all the dependencies installed :) If you need further
assistance, check out our list at
http://lists.own-hero.net/mailman/listinfo/devel-spam
Once I get more time, I will also be able to do more work on the wiki :)
Best regards,
Chris
