Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] The present invention adopts different parameters to embedding with different strengths under different prediction complexity situations. In the case of the same recognition degree of human eyes, the purpose of stronger robustness and resistance to compression and other attacks is achieved.

[0041] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0042] like figure 1 As shown, the reversible robust digital image watermarking method conforming to the human eye observation law provided by the embodiment of the present invention inc...

Abstract

The invention belongs to the digital watermarking technical field, and discloses a reversible robustness digital image watermarking method complying with human eye observation rules; the method uses different parameters to embed with different intensities under different predicted complexities, thus providing stronger robustness under the human eye same identification level to resist compactions; the method sets different parameters according to the complexity prediction before embedding into the grey-scale image, carries out embedment with different intensities on different blocks according to the histogram, thus better complying the human eye observation rules in certain level, providing small extraction error rate while having higher SSIM (composition similarity) value, i.e, higher robustness. The method can be also applied to the secret information concealing.

Description

technical field [0001] The invention belongs to the technical field of digital watermarking, and in particular relates to a reversible and robust digital image watermarking method conforming to the observation rules of human eyes. Background technique [0002] In recent years, in the fields of military, medical, remote sensing image processing, etc., the original digital image is analyzed, and the value of some pixels is changed reasonably, so that the image quality does not decline significantly after the watermark is embedded, and it can be processed at the extraction end. Reversibly restore the original image and correctly extract the embedded watermark. However, it is often difficult to guarantee that the embedded image will not be changed before receiving it at the receiving end. JPEG compression is a very common change to the image. Due to the needs of transmission and storage, etc., sometimes JPEG compression has to be performed, and compression will cause changes in...
