Abstract
U ovom radu obrađen je pojam testa CAPTCHA koji se koristi za prevenciju automatiziranih programa koji svojim djelovanjem mogu sniziti kvalitetu sustava koji se štiti. Također je razrađena ideja umjetne neuronske mreže te učenje iste. U skladu rada napravljen je prototip za savladavanje jedne odabrane vrste testa CAPTCHA. Izrađena je programska implementacija koja koristi algoritme uklanjanja šuma i segmentacije znakova kako bi pripremila znakove za klasifikaciju naučenoj umjetnoj neuronskoj mreži.
Abstract (english)
This research paper describe introduces term CAPTCHA (an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart") which is used to prevent automatized software to decrease quality of server which CAPTCHA tests protects. It also describes artificial neural networks, as well how to train one using backpropagation algorithm. Prototype implementation of software which was created to solves one type of CAPTCHA is described, along with algorithms for clutter removal and symbol separation which are used.
