Toward High Capacity and Robust JPEG Steganography Based on Adversarial Training

Table 1

The image quality and decoding accuracy of embedding secret messages with different payloads in the case of no attack. The embedded secret messages come from MNIST dataset, and the size of them are adjusted to by Matlab. “Decoding_acc” means the decoding accuracy.
