Abstract

The present application relates to an image processing method, device storage medium and computer equipment. The method includes: acquiring a frequency-domain labeled image; the frequency-domain labeled image is obtained from a spatial-domain labeled image through frequency-domain transformation; Transparency parameters correspondingly configured for the marked image; acquiring target page data; performing layer overlay rendering of the frequency-domain marked image and target page data according to the transparent parameters. The solution provided by this application can effectively protect target page data.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] Digital watermarking technology is to embed marking information into digital carriers (such as multimedia, documents, software, etc.) to be protected. With the development of computer technology, digital watermarking technology is more and more widely used in the fields of data protection and data tracking. . Traditionally, when using watermarks to protect images, documents, or pages, the spatial domain watermark images are usually directly overlaid on the images, documents, or pages to be protected. However, using this method of spatial domain watermarking generally makes the color of the watermark and the original image have a color difference, which is easy to be perceived by users. [0003] With the traditional spatial domain watermarking method, since the content and location informatio...
