Effects and solutions of Cover-Source Mismatch in image steganalysis

作者：

Highlights：

• This paper identifies the main causes of CSM via a systematic study

• CSM is defined clearly from a statistical signal processing perspective

• All possible sources of CSM are assessed from acquisition to compression

• We show that, by far, the processing pipeline contributes the most to CSM

• Finally we also present compare two strategies to cope with the CSM
