FORGERY ANALYZER AND THE METHOD OF DIGITAL IMAGE

摘要

A forgery analyzer and a method thereof are provided to classify a plurality of pixels comprising a digital image based on a reference correction coefficient which is a transparent reference to analyze forgery of the digital image, thereby accurately detecting forgery. An input image comprised of a plurality of pixels is received(20). A correction coefficient applied to a plurality of pixels is detected(30). A plurality of pixels is classified into the first group pixels corrected by the reference correction coefficient and the second group pixels not corrected by the reference correction coefficient(60).
