Zusammenfassung
This paper presents a robust coin recognition method with rotation
invariance. The rotation invariance feature is represented by the
absolute value of Fourier coefficients of polar image of coin on
circles with different radii. The absolute value of Fourier coefficients
is considered as the individual feature of the particular coin. Moreover,
in this paper, the variations on surface of coin such as light reflection
effect, are taken into account. Such variations effect can be reduced
using the Fourier approximation of the coin image. Finally, coin
can be recognized by the distance between the absolute value of Fourier
coefficients obtained from the reference coin and the coin to be
recognized. The coin recognition experiments are given to show the
effectiveness of the proposed method
