Embodiment Construction

[0097] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0098] Such as figure 1 As shown, a kind of reversible skin color smoothing method with reversible information hiding function described in the present invention, comprises the following steps:

[0099] The first step is to obtain the original image. Obtain the original image to be processed, because the image on the network is basically a color image at present, so the original image to be processed obtained here by the present invention is a color image, and all inputs are three channels of RGB, and the method of the present invention is used in practical applications It can also be extended to grayscale images.

[0100] The second step is the hiding of secret information. According to the characteristics of each channel of the t...

Abstract

The invention relates to a reversible skin color smoothing method with a reversible information hiding function and an original image recovery method thereof. Compared with the prior art, the reversible skin color smoothing method solves the defects that hidden information is easy to find and skin color smoothing processing is irreversible. The method comprises the following steps: obtaining an original image; hiding the secret information; extracting a skin color region; performing reversible skin color smoothing. According to the invention, a behavior hiding effect of skin color smoothness is realized; Namely, the original content is hidden by the face beautification image with the high visual quality characteristic, and the hidden information and the skin color are smooth and reversible, so that the attention and doubt of an attacker on the secret-carrying image are reduced, the possibility that the secret-carrying image is attacked is reduced, and the security of the image is further improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a reversible skin color smoothing method with a reversible information hiding function and an original image restoration method thereof. Background technique [0002] With the rapid development of social networks and smart phones, people are more and more keen to share their own life photos on the Internet, which also promotes the extensive development of facial skin smoothing algorithms. A variety of skin tone smoothing algorithms for human faces are technically unable to restore the original image, which means that users cannot restore the original image losslessly from the smoothed image. [0003] In the prior art, although there are beautification image restoration methods for PS, Meitu Xiuxiu and Instagram, the portrait image restored by this method is only visually similar to the original image, not consistent with the original image. In some application scenarios...
