| abstract
(eng) |
When two or more images are spliced together, to create high quality and consistent image forgeries, almost always geometric transformations such as scaling or rotation are needed. These procedures are typically based on a resampling and interpolation step. In this paper, we introduce a blind method capable of finding traces of resampling and interpolation. We also propose a novel method capable of dividing an investigated image into various partitions with homogenous noise levels. |

V případě, kdy dva nebo více obrazů jsou skládány dohromady, a požadujeme kvalitní a reálný výsledek, pak většinou je třeba aplikovat geometrické transformace. Tyto procedury jsou založeny na převzorkování a následné interpolaci. V tomto příspěvku představujeme pasivní metodu umožňující nalést stopy po převzorkování a interpolaci. Je také navržena metoda, která rozděluje obraz na části s homogenní úrovní šumu |
