In order to capture the changes of statistical features of images caused by stegography more comprehensively and improve the detection accuracy of spatial steganalysis, the embedding characteristics of the steganographic algorithm are incorporated. The derivative and Gabor double filter is used to preprocess the image, and the filter extraction is enhanced to produce a variety of residual images, which effectively increases the diversity of steganographic features. The optimized CBAM module is embedded into the residual block to guide the network to effectively focus on the region with rich steganographic signals, thus strengthening the discriminant learning ability and training effect of the network. The proposed model is compared with the classical model on BOSSbase v1.01 and BOWS2, and the experimental results show that the detection accuracy of the proposed method is superior to the existing mainstream models of Ye-Net, SRNet and ZhuNet.
