Embodiment 1

[0042] In this embodiment, a method for image reversible information hiding based on attention guidance is disclosed, including:

[0043] get the original image;

[0044] Divide the original image into a fork set image and a point set image;

[0045] Obtain the predicted point set image through the cross set image;

[0046] Perform hidden data inversion on the point set image and the predicted point set image to generate a point set data hidden image;

[0047] Obtain the predicted cross-set image through the hidden image of the point set data;

[0048] Perform hidden data inversion on the fork set image and the predicted fork set image to generate a fork set data hidden image;

[0049] The point-set data-hidden image is fused with the cross-set data-hidden image to obtain the data-hidden image.

[0050] Further, input the cross-set image into the point-set image prediction model to obtain the predicted point-set image;

[0051] The hidden image of the point set data is in...

Abstract

The invention discloses an image reversible information hiding method and system based on attention guidance. The method comprises the steps of obtaining an original image; dividing the original image into a cross set image and a point set image; obtaining a predicted point set image through the cross set image; performing hidden data inversion on the point set image and the predicted point set image to generate a point set data hidden image; obtaining a predicted cross set image through the point set data hidden image; performing hidden data inversion on the cross set image and the predicted cross set image to generate a cross set data hidden image; and fusing the point set data hidden image and the cross set data hidden image to obtain a data hidden image. Accurate and reversible information hiding of the image is realized.

Description

technical field [0001] The invention relates to the technical field of reversible information hiding, in particular to an attention-guided image reversible information hiding method and system. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the rapid development of communication technology, reversible information hiding [RDH] technology has become an inseparable part of people's life, but the embedding capacity and the visual quality of images have always been a dynamic problem in RDH. Reversible information hiding (RDH) techniques are known for not losing original images and information. Information hiding is a technique that embeds information into multiple media and extracts the data without error with minor modifications to the overlay media. In order to protect the overlay medium, a RDH algorithm which can detect the overlay ...
