Il incercasem si pe asta; intr-adevar cu ini-ul tau am o oarecare rata de succes - din 22 de imagini mi-a "ghicit" cam 5.

Ce fel de catcha ii asta ? Rata mai buna de atat nu se poate ?

[SETUP]
;###############################################################################
;###### just some information for the user
;###############################################################################

;name of the system that uses this captcha
engine name=ANAF

;what type is this engine (e.g. Guestbook, Social Boomark, Blog...)
engine type=Unknown

;a small description
description=

;how good is this setup to break the captcha in percent?
success rate=40

;accept results where the chars are different but look the same like O=0
accept same looking chars=0

;a image to show as sample
sample captcha=.\x6x62.jpg

;a sample site that uses this...
sample url=

;a icon that we should display in list (else we use the icon of the category)
icon file=

;###############################################################################
;###### how to identify the captcha to this setup
;###############################################################################

;other names that external software might use as platform (seperate by ,)
;this is for programs that send the platform to us with the captcha image to make 
;identification easier 
alternative names=

;dimensions that this captcha has... e.g. 100x40, 100-200x40-50
image dimension=200x50

;can be gif, jpg, png, bmp (leave empty to accept all)
image type=jpg

;if all the above methods still match more than one setup
;we analyse the background colour and match it against the one in the list
;it's a hex value with RRGGBB (red, green, blue)
main background color=EEEEEE, C6C6C6, DADADA, F8F8F8, CECECE

;###############################################################################
;###### setting for the OCR
;###############################################################################

;what charsets are used in that captcha...
;by default its A-Za-z0-9 and some symbols. Add them all and no ranges
charset=0123456789abcdefghijklmnopqrstuvwxyz

;how short/long is the word that the captcha is delivering
min length=5
max length=5

;what orc to use (auto (all), gocr, cube, tesseract, [more to follow])
ocr to use=auto

;when more than one OCR seems to deliver a good result we have to decide which one to take
;usually this is done automatically but for some engines it makes sense to set it fixed.
prefered ocr=OCR2

;after the ocr engine delivers a result we might want to change certain things...
;ocr replace=A;4|B;8|C;0
;ocr remove="captcha presented by xyz"

;maybe the captcha has always one char that is always present...
;thats the case for math captchas e.g....if that + or - sign in not there we have a wrong result
;ocr must have=+|-

;instead of using OCR we use a fixed hash for each char that we compare
use fixed chars=0

;when "use fixed chars=1" is used, we might still try to solve by filters (useful for programs that reencode 
;to jpg with low quality and noise in resulting image)
try to solve by filter=0


;instead of using OCR we make a crc32 of the image and compare it with the one we have stored
use fixed results=0
use min size=0
min size=3385
use max size=0
max size=3492
use mask chars=0


;this is an advanced option where you can make a CRC32 of a fixed image (file content) and
;set a result here. syntax: <crc32>=<result> 
;make sure you remove the comment of this section if you use this
;4CA39E3F=JANINE

;the real thing starts here...

[fixed chars]
box start x=0
box start y=0
box height=42
box width=42
apply image filters=0
try to solve by filter=0

[mask chars]
try to solve by filter=0
apply image filters=1
min match score=70
[PROCESSING1]
-mask mask_blots.png
-scale 107.0%
-scale 60.0%
-threshold 47%
-shave 1x1
-scale 278%
-negate
-black-threshold 45%

Suporta server emulator + multe alte chestii.

Scuze pentru dublu post, eu avusesem rata de 100% la 5 imagini dar la 20 de imagini rata a fost mai mica, am refacut modulul pentru o rata mai buna de detectie.

Nu stiu ce captcha este, nu te poti lua dupa modulul de detectie ca e cam aiurit.

Si pentru OCR facut in 5 minute, e destul de buna si rata asta de detectie, daca nu iti convine, baga dbc si gata, ca sa ti-l fac standalone fara nimic si cu o rata mult mai buna de detectie, ar trebui sa iti iau 500-700e.
