Embodiment Construction

[0231] 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:

[0232] like figure 1 As shown, a kind of medical image reversible information hiding method based on multi-texture division described in the present invention comprises the following steps:

[0233] The first step is to obtain the original image, and obtain the original medical image to be processed.

[0234] The second step is the embedding process. Perform histogram stretching on the original medical image to distinguish high-texture level pixels and low-texture level pixels, and perform high-texture level information, low-texture level information, and auxiliary information embedding processing respectively. The specific steps are as follows:

[0235] (1) Perform histogram stretching on the original image. In order to make the ...

Abstract

The invention relates to a method for reversible information hiding of medical images based on multi-texture division, which solves the defect that there is no reversible information hiding for medical image characteristics. The present invention comprises the following steps: acquisition of the original image, obtaining the original medical image to be processed; embedding process, stretching the histogram of the original medical image, distinguishing high-texture level pixels and low-texture level pixels, respectively performing high-texture The embedding processing of high-level information, low-texture high-level information, and auxiliary information; the acquisition of secret-carrying images, the processed secret-carrying images are obtained through the embedding process. The invention realizes the contrast enhancement reversible information hiding method which does not depend on the embedding rate and has the characteristic of high embedding capacity.

Description

technical field [0001] The invention relates to the technical field of image information hiding, in particular to a method for reversible information hiding of medical images based on multi-texture level division. Background technique [0002] In recent years, reversible information hiding has received extensive attention. Reversible information hiding is to embed secret information into the original carrier (such as image, video) to obtain the same quality as the original carrier or higher visual quality of the original carrier, and then the decryption party extracts the secret information from the secret carrier without loss. restore the original carrier. In short, reversible information hiding is to embed information into the carrier while ensuring that the decryption party can extract the secret information and restore the original carrier without loss. The reversible information hiding technology can ensure the lossless restoration of the carrier after extracting the ...
