I am new to CB and currently testing it's capabilities. I got a service which has two captcha versions - is it possible to detect this in CB? or will I have to detect it beforehand? (detection is rather easy since background is white with one version and gray with the other).
here's a zip file with some samples, V1 was unsolvable for CB, V2 got some solved, currently running bruteforce on V2 only to see how good the solved rate might get.
Thank you for your help in advance
