Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0036] Such as figure 1 As shown, the embodiment of the present invention is a mosaic image synthesis method, including:

[0037] Step 110: Pre-select multiple original images as an image library;

[0038] Step 120: Take an original image from the image library as the main image;

[0039] Step 130, if there is no secondary mosaic image, take an original image from the image library as the secondary mosaic image, and implant the secondary mosaic image into the main image to obtain the implanted main image; otherwise, the implanted main image Replace the secondary mosaic image, implant the secondary mosaic image into the main image to obtain the implanted main image;

[0040] Step 140: If there are still original images in the image library, perform step 120, otherwise end.

[0041] The image selection needs to have a certain order, and the im...

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 invention relates to related technical fields in the fields of information security and signal processing, in particular to a mosaic image synthesis method and device. Background technique [0002] 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 transmitting the secret information by hiding the secret information in the openable media information. [0003] Information hiding technology is divided into steganography and digital watermarking. At present, the research of information hiding technology mainly focuses on the research of digital watermarking technology. The digital watermarking algorithm has gone through the development process from spatial domain watermarking algorithm to transform domain watermarking algorithm, from non-blind watermarking algorithm to blind watermarking algorithm...
