Embodiment 1

[0030] Please refer to figure 1 , the embodiment of the present application provides a robust invisible digital image watermarking method, including:

[0031] S101: Preprocessing the watermark image;

[0032] S102: Preprocessing the host image;

[0033] S103: watermark embedding;

[0034] S104: Generate a watermarked image to obtain a watermarked color image.

[0035] A strong and robust invisible digital image watermark processing method adopted in the present invention can be applied to intelligent electronic devices, such as smart phones, etc., and the intelligent electronic devices have data input and output parts, and have data processing capabilities. The above method can also be applied to a server or computer system in a general sense.

[0036] When the method is executed on an intelligent electronic device, a server or a computer system, S101 is executed to preprocess the watermark image.

[0037] In digital watermarking, it is not unsafe to encrypt the watermark...

Abstract

The invention discloses a strong robust invisible digital image watermark processing method and device. By preprocessing the watermark image, preprocessing the host image, embedding the watermark and generating the watermark image, a color image containing the watermark is obtained. It can effectively improve the fidelity of the watermarked image, resist external interference performance, and balance the invisibility and robustness of the watermark.

Description

technical field [0001] The invention relates to the technical field of digital image copyright protection, in particular to a robust invisible digital image watermark processing method and device. Background technique [0002] Image digital watermarking technology, as a new digital image copyright protection method, is more and more closely related to all walks of life. It plays a pivotal role in the fields of national military secrets, medical images, commercial propaganda, industrial production, and information security. The existing watermark embedding algorithm is relatively simple and does not need any transformation of the original image, so the time complexity is low and the watermark capacity is large. But it only has good resistance to image compression attacks, and is less robust to noise interference. Contents of the invention [0003] In order to solve the above problems, the present invention provides a strong robust invisible digital image watermark processi...
