碩士 === 國立交通大學 === 資訊科學學系 === 86 === This thesis applies the image processing technique to develop algorithms for recognition of the real coin. I hope we can implement hardware based on the ideal algorithms for public phones and vending machines to avoid to get the tokens from the TV Games in order to make better profit.Those algorithms are categorized in two parts. The first one uses the characteristic values to analyses the head or tail of the coins. The second one uses the cycle contrast to recognize the rims of the coins. This thesis includes all algorithms forcoin recognition, the detailsand the result of the experiment. Besides the algorithms mention above, we also focuses on the low error rate algorithm. Itmay become the trend for the future development of hardware.
