CS297 ProposalNeural net Captcha Cracker.Geetika Garg(geetikagarg07@gmail.com) Advisor: Dr. Chris Pollett Description: A CAPTCHA (an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart") is a type of challenge-response test used in computing to determine whether or not the user is human. In this project, I will be working with Dr. Pollett on neural networks to crack CAPTCHAs. In the end, we will be able to make a program removes the effects and noise from an image and then will use neural nets to recognize a CAPTCHA. We will be training a large sample of data on neural nets to build our OCR. Schedule:
Deliverables: The full project will be done when CS298 is completed. The following will be done by the end of CS297: 1. Python program to read and clean up image 2. Literary review on Captchas 3. Program implementing OCR 4. Results of training a data set through neural nets. 5. Complete 297 report. References: David R. Martin, Charless C.
