Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Such as figure 1 As shown, the embodiment of the present invention is a mosaic image synthesis method, including:

[0038] Step 110, selecting a plurality of original images in advance as an image library;

[0039] Step 120, taking an original image from the image library as the main image;

[0040] Step 130, if there is no secondary mosaic image, then take out an original image from the image library as a secondary mosaic image, and implant the secondary mosaic image into the main image to obtain the main image after implantation; otherwise, insert the main image after implantation Replacing the secondary mosaic image, implanting the secondary mosaic image into the main image to obtain the main image after implantation;

[0041] Step 140, if there are still original images in the image library, then execute ...

Abstract

The invention relates to the technical field related to the field of information safety and signal treatment and particularly relates to a synthetic method for a mosaic image and a device thereof. The synthetic method comprises the following steps: selecting a plurality of original images as an image library in advance; selecting one original image from the image library as a main image; if no secondary mosaic image exists, selecting one original image from the image library as the secondary mosaic image and embedding the secondary mosaic image into the main image so as to obtain the main image after being embedded; and otherwise, replacing the main image after being planted by the secondary mosaic image and embedding the secondary mosaic image into the main image. According to the synthetic method provided by the invention, the problem of hiding and transferring of more information is solved. A multilayer mosaic image can be utilized to realize the hiding of multilayer information as well as the hiding and transferring of more information. The multilayer mosaic image has a potential application value in a series of applications, such as information hiding, image retrieval, computer art, philosophy, computer simulation, scene conversion, image transferring, and the like.

Description

technical field [0001] The present invention relates to the relevant technical fields of information security and signal processing fields, in particular to a method and a device for synthesizing a mosaic image. [0002] Background technique [0003] Information hiding is a method proposed in the field of information security and signal processing to solve information security. It achieves the purpose of verifying the data integrity of the media information or delivering the secret information by hiding the secret information in the publicly available media information. [0004] Information hiding technology is divided into steganography and digital watermarking. Currently, the research on information hiding technology mainly focuses on digital watermarking technology. Digital watermarking algorithms have experienced the development process from spatial domain watermarking algorithms to transform domain watermarking algorithms, from non-blind watermarking algorithms to bli...
