Abstract

In this study, a practical forensics aided steganalyzer (FA-steganalyzer) for heterogeneous bitmap images is constructed, which can properly handle steganalysis problems of mixed image sources including raw single-sampled images and resampled images at different scaling factors. The proposed FA-steganalyzer consists of a resampling detector followed by two corresponding steganalyzers, one of which is used to deal with raw single-sampled images and the other is used for mixed resampled images at different scaling factors. Extensive experimental results show that the proposed FA-steganalyzer outperforms the existing steganalyzer that is trained on a mixed dataset especially at low embedding rates.
