Claim 8:
9. A system for large-capacity image recovery based on an invertible neural networks, wherein the system for large-capacity image recovery is applied to the system for large-capacity image steganography according to any one of claim 5, the system for large-capacity image recovery is implemented based on the invertible neural networks, and the invertible neural networks comprises invertible modules which comprises a host branch and a hidden branch, the system for large-capacity image recovery comprising:
an input module, configured to input a stego image and a constant matrix, wherein the stego image is an image obtained by embedding feature information of a hidden image into a host image, and the constant matrix does not contain effective information of the hidden image;
an information separation module, configured to separate features of the hidden image and the host image from the stego image through reverse mapping of the invertible neural networks;
a host image output module, configured to reversely output a recovered host image by utilizing a host branch of the invertible neural networks; and
a hidden image output module, configured to reversely output a recovered hidden image by utilizing a hidden branch of the invertible neural networks.
