Skyté periodicity v interpolovaných signálech a jejich derivacích
 Saic, Stanislav ; Mahdian, Babak
Many applications like, texture analysis, image registration, etc., are based on interpolation. Therefore, without the detailed knowledge of how the statistics of the signal is changed by the interpolation process, applications based on statistical approaches working with interpolated signals or with their derivatives can yield miscalculations and unexpected results. Therefore a detailed knowledge about the changes brought into the signal by interpolation could be critical. Sometimes, there exists a need to examine whether a signal has been interpolated.
