i tried DFS approach. but the time is over and some bug(?) or errors are developed. may i ask the solver some more hints?
maybe needed BFS? the differentiation of the eye from surrounding circle is done, but in some cases, not..
needed operant conditioning.

so hard… :)

Edit) thanks for reply. i passed other way possibily hardly. i must know more deep.

This was was quite difficult. I implemented an ANN to solve that.

darkl33ch, I have made a post in solutions section.

In two words you separate your captcha to symbols, then make a vectors from each symbol. Also you must have your “training set”, make vectors from those pics too, then compare. Sounds much like brute force :) See the article in my post, it explains much more clearly then I do :)

Seems like you did what I did, except I used an ANN on each symbol. Cool.
