can you provide URLs to each captcha? Because the images are named *.pgn but are actually jpg...I would want to set the correct image type to them.

sorry.. i forgot it.. And you are right... I added the end ".PNG" to the name of the file but actually i don´t know the kind of the image.

Hi Sven... Please don't forget about me... I was expecting your help about this 3 new captchas definition.  Unfortunately the web page changed the condition of the captcha (the captcha changes every time and i can't save it into GSA CB) and i had to change the format to save it.  Right now i have PNG files and the size seems to be different.

Today I only have 2 sort of captchas.  The new files are here.  Sorry if i bother you..

The web page is this:

And the link of the moved captcha is this:

I tried to make my own captcha definition using "brute force method" but I only got 20% success rate.  I think it needs tune

Sven

Yes have this already prepared for the next update. Try and import THIS it with right click->import->from url

Thank you very much Sven.. CB is such an amazing program.!  One last question: Is there any way to improve the already good success rate of CB?  Perhaps expending time answering a lot of captchas (one or two  thousand) and then apply USE MASK or another way?

Sven

yes there is always room for this. If you can get more samples, then the Mask function will most likely break it close to 100%. However this is also taking longer the more samples you have added to the db.

Is there any way to tune the character recognition?  Right now i have a problem with  the recognize the character 1 and I, 1 and J, 2 and Z, 5 and S, 8 and B, C and G, D and O.

The success rate of CB said 38% but actually the successes are 17%, basically due to this characters...

Will you tell me some way to fix it...?

Sven

Hmm the more samples you have for the Mask algorithm, the better it should get. Maybe optimizing the filters a bit more would also help.

Thanks Sven... I leave new links with new set of captchas. The difference that the first that I gave you is this is save it in PNG format and the size seems to be different.
