摘要： Systems and associated methods for coin discrimination are disclosed herein. In one embodiment, a method for discriminating coins includes obtaining an electromagnetic sensor signal of a coin, sampling the sensor signal, generating a fingerprint of the coin from the sampled sensor signal, and calculating an appraisal using the fingerprint and a linear discriminant vector. The appraisal can be compared to a threshold to determine whether the coin is valued or impostor. In some embodiments, the linear discriminant vector can be calculated using the valued and impostor coin populations' covariance and means.

摘要： Systems and associated methods for coin discrimination are disclosed herein. In one embodiment, a method for discriminating coins includes obtaining an electromagnetic sensor signal of a coin, generating a contour signal by digitizing the sensor signal, identifying an active interval in the contour signal by eliminating the segments of the contour signal which are close to zero, and detecting the coin approach, pivot and departure points (coin features) from the contour signal in the active interval. The coin features can be compared to known values for different coins to discriminate the coin.
