p3n1 · 10-10-2010, 03:36 PM

I've written a recaptcha distortion remover and now i'm able to download with jDownloader from HF and FS (and most likely from all other sites using reCAPTCHA).

New Version 0.2c - got 17% recognition rate!

the combined module for jDownloader can be downloaded here.
hope u can use this stuff

Thank you for this. Not trying to flame, but since you've posted it, Google will probably fix it very soon.

cah · 10-11-2010, 02:29 PM

Thanks. What fraction of captchas can it decode?

Thanks. What fraction of captchas can it decode?

if you mean by fraction which recognization rate it has: around 5%... thats not that much but i'm working on it. and should be enough if you use proxies because of the ~32 wrong guesses google gives you.

if they fix it, i got something to do - and lets be clear: i totally want them to get better, cause its the only spam stopping mechanism out there atm.

it seems to me that the result is far from being impressive, not bad though

thx for your reply! you're absolutely right, it could be far better - that's what i hope for. i haven't implemted all of chad's algorithms yet and the parameters

Code:

$contrast=128;
$maxslope=-1;
$mid_exponential_smoothing_factor=0.2;
$vector_exponential_smoothing_factor=0.001;

aren't the best fit by now. but i think it's a good point to start from.
but feel free to play around with them and post your results afterwards!

little update:
i get better results (around 9%) with these parameters:

Code:

$contrast=112;
$mid_exponential_smoothing_factor=0.1;
$vector_exponential_smoothing_factor=0.04;

At last someone who reallly tries to deal with this annoying problem.

I hope you'll soon reach at least 50% hit rate

Currently in v0.2a hotfile.com ACR isn't working for me he's asking to enter it manually.

KEEP UP THE GOOD WORK BUDDY

thx for the motivation

but i think 50% will never be reached - there are too many variations...

jDownloader deletes the 'hotfile.com' folder everytime it starts, so you'll have to set the ntfs permissions to read-only for the usergroup "everyone" or just take another hoster, because hotfile got a 1 min delay between captchas

Pretty useful if you have the proxies. That said decaptcha is pretty cheap so not sure I will make any use of it.

Could you PLZ explain , what proxies are you talking about ?

DeCaptcha is the site decaptcher.com ? he deals with google's ReCaptcha aswell ?

sorry for being a noob but can anyone help me set this up in English?

coldasice · 10-20-2010, 04:37 AM

sorry for being a noob but can anyone help me set this up in English?

To add the module to jDownloader, the archive must be extracted to the folder "installation folder * * jdownloader \ jd \ captcha \ methods \

for the meanwhile return to manual (user) AntiCaptcha after X auto AntiCaptcha mishits ?

Currently I have to cut out HF and FS folder out to do so.

We need the %s up at least to 25%.
FS (and maybe HF) gives a plugin error after +/- 10 failures and move on to the next file so there goes my night DL

I don't know how you work on this but if the algorithm isn't common to all hosters I really really suggest that you focus on the main 2:
FileServe and Hotfile. Anyway how are things progressing ?

I'm really crossing my fingers for you

Sorry I'm a noob here but can you explain me step by step what should I do to use it for a specific website.

Thanks
