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 restoration method thereof. Compared with the prior art, the defects that hidden information is easy to be found and skin color smoothing processing is irreversible are solved. The invention comprises the following steps: acquisition of original image; hiding of secret information; extraction of skin color area; reversible skin color smoothing process. The invention realizes the behavior concealment effect of smooth skin color, that is, hides the original content with a face beautification image with high visual quality characteristics, and the hidden information and smooth skin color are reversible, which reduces the attacker's attention and effort to the secret image. Suspicion reduces the possibility of the confidential image being attacked, thereby further improving the security of the image.

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...
