Capture Breaker 2.68 bugs

dimzon541

I'm evaluating Capture Breaker v 2.68 and facing such bugs:

1)  There are "recogntion log" in the bottom of main window - seem's like it shows wrong time (seem's like it shows HH.MM.MM instead of HH.MM.SS)

2)  I'm posting captcha to /gsa_test.gsa. I wrote simple code in C# to send same PNG 100 times in loop. Surprise - some attemps are failed ("recogntion log" shows whole white rectangle instead original capture). Seems like there are some racing conditions on my slow Intel Atom Netbook (adding 1 seconds delay between attempts solve the problem)... My source is here

1) where exactly? I had a look at source but it's always hh:mm:nn (nn is your ss).

2) what types of captchas do you send?

dimzon541

1) I doesn't have your source - i'm looking at bottom in main window. There are really 1 seconds delay between I send captcha to captcha breaker (but all of them are shown as 23:26:26

2) the captcha is custom.

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

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

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

;a small description
description=

;how good is this setup to break the captcha in percent?
success rate=66

;accept results where the chars are different but look the same like O=0
accept same looking chars=1

;a image to show as sample
sample captcha=.\15042.png

;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=150x50

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

;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=F8F8FF, 000000, 7C7C7F, EBEBF2, 070707, 111111, FF1010, 191919, 303031, FC7C7F, DEDEE5, 242425, 3F3F41, FAAAAF, FD3E40, 383839, 646467, FE1F20, F9D9DF, FB9B9F, D6D6DC, 474749, F9CDD3, C4C4CA, FABABF

;###############################################################################
;###### 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=0123456789

;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=3319
use max size=0
max size=4606
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: =
;make sure you remove the comment of this section if you use this

;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]

this is how "racing condition" effect looks like (trust me I'm reading whole capthca into memory then just post them into loop so there are no way I send white rectangle instead actual captcha)

Sven

OK will have a look. Can you send me the captchas you submit to it?

Sven

the time is indeed wrong and I have fixed that for next update.

dimzon541

In my test I'm posting only one picture as captcha http://i62.tinypic.com/v42dz4.png

dimzon541

can't find filter documentation ;(

I need to remove "red" scratches from captcha. I need to replace all pixels where R > E0 and G < A0 with white

how to do this?

Sven

use exchange colour
