| Summary: | 碩士 === 國立交通大學 === 多媒體工程研究所 === 103 === Nowadays counterfeit money has increased to an unacceptable level in Taiwan, especially for fifty dollar coins. As the techniques of counterfeit become more advanced, many traders cannot effectively distinguish the money between authentic or counterfeit. In order to prevent the counterfeit money from running rampant, we propose an image analysis method based on the change of specular reflection of a coin. It is verified through experiments that the proposed approach, and the implement prototype machine, can effectively and efficiently distinguish authentic and counterfeit coins. We hope the proposed approach can prevent effectively suppress the amount of counterfeit money in our society.
