cas_special	research CEZ:AV0Z10750506 abstract (eng) 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. abstract (cze) Řada aplikací jako texturní analýza, registrace obrazů a další jsou založeny na interpolaci. Detailní informace o změně statistických vlastností interpolovaného signálu a jeho derivací může pomoci při identifikaci zda a jak byl zkoumaný signál interpolován. reportyear 2007 RIV JD permalink http://hdl.handle.net/11104/0144937 arlyear 2007 mrcbU10 2007 mrcbU10 Praha ÚTIA AV ČR
