Machine Vision Algorithm Advances

TechCrunch: Google Street View team reports that its recent text and street numbers recognition algorithm can be successfully used for solving CAPTCHA puzzles widely used on the web to determine a human versus a spam bot. The algorithm has been presented in a paper at the International Conference on Learning Representations (ICLR).

I have a feeling that this algorithm has leaked outside Google, as starting from about Sept. 2013 the amount of spam comments in this blog has grown dramatically. On same days, per each real comment I get 10 spam ones, in spite of CAPTCHA protection.

Google algorithm recoginizes this with 99.8% accuracy
