Embodiment Construction

[0232] 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:

[0233] 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:

[0234] The first step is to obtain the original image, and obtain the original medical image to be processed.

[0235] 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:

[0236] (1) Perform histogram stretching on the original image. In order to make the ...

Abstract

The invention relates to a multi-texture-degree-division-based reversible information hiding method of a medical image so that a defect of lack of hiding of reversible information hiding for the medical image characteristics can be overcome. The method comprises: step one, acquiring an original image; to be specific, acquiring a to-be-processed original medical image; step two, carrying out embedding; to be specific, carrying out histogram stretching on the original medical image, distinguishing a high-texture-level pixel and a low-texture-level pixel, and carrying out embedding processing ofhigh texture level information, low texture level information, and auxiliary information; and step three, acquiring a secret-carried image; to be specific, acquiring a processed secret-carried image by an embedding process. According to the reversible information hiding method with the enhanced contrast, dependence on the embedding rate is avoided and the embedded capacity characteristic is high.

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 ...
