| description | The invention discloses a method and system for hiding an image with an image based on a pixel-level reward mechanism, and the method comprises the steps: inputting a color carrier image and a gray secret image into a trained image hiding network during the hiding of a secret image, and generating a secret-containing image; when a secret image is extracted, inputting the secret-containing image into the trained image-hiding-image network to obtain a reconstructed secret image; the image hiding and image network training comprises the following steps: constructing an image hiding and image network by using an image cascade hiding network, a reconstruction network based on a U-Net + + structure and a judgment network; according to the loss function of the image cascading hidden network, the loss function of the reconstruction network based on the U-Net + + structure, the judgment result of the judgment network and the pixel-level reward matrix, constructing a total loss function of the image hiding network; and |
