CAPTCHA OCR

I need an algorithm to OCR CAPTCHA Images, Programming language is not a must, the algorithm should take a bit matrix with ones and zeros that represents the CAPTCHA to be OCRed: String OCR( boolean[][] image){ //OCR the image return text; } CAPTCHA Samples: Check the attached images Note: The implementation must be independent, I am asking for a function as described in the signature above Please if you have no experience in the field I appreciate not to bid, so we can save our times Cheers ## Deliverables Please consider optimized algorithm
