Toward High Capacity and Robust JPEG Steganography Based on Adversarial Training

Figure 8

The PSNR and SSIM of different payloads with different JPEG quality factors. As the payload increases, the PSNR and SSIM are decreasing, and it shows that image quality would decrease with a bigger payload. (a) PSNR. (b) SSIM.
