As both features extraction and classification steps are perfectly embodied in the deep learning architecture called Convolutional Neural Network (CNN), different studies have tried to design a CNN-based steganalyzer. This work proposes a criterion to choose either the CNN designed by Xu et al. or the combination Spatial Rich Models (SRM) and Ensemble Classifier (EC) for an input image. Our approach is studied with three steganographic spatial domain algorithms: S-UNIWARD, MiPOD, and HILL, and exhibits detection capabilities better than each method alone. As SRM+EC and the CNN are only trained with MiPOD the proposed method can be seen as an approach for blind steganalysis. %G English %Z TC 11 %2 https://inria.hal.science/hal-01649001/document %2 https://inria.hal.science/hal-01649001/file/449885_1_En_22_Chapter.pdf %L hal-01649001 %U https://inria.hal.science/hal-01649001 %~ CNRS %~ UNIV-FCOMTE %~ UNIV-BM %~ ENSMM %~ FEMTO-ST %~ UNIV-BM-THESE %~ IFIP %~ IFIP-AICT %~ IFIP-TC %~ IFIP-TC11 %~ IFIP-SEC %~ IFIP-AICT-502
