Abstract

The invention provides a watermark adding method and device and electronic equipment in the technical field of image processing. The watermark adding method comprises the following steps: carrying outnoise processing on a first watermark in different directions to obtain a plurality of watermark patterns, and carrying out noise processing on the first watermark in different levels in the same direction to obtain one or more of the plurality of watermark patterns; obtaining a first pixel value of a preset area of the multiple watermark styles, and obtaining a second pixel value of a first image to which watermarks are to be added; and superposing the first pixel value and the second pixel value to obtain a plurality of types of second images, the different types of second images includingdifferent watermark patterns. According to a watermark adding scheme provided by the invention, the anti-theft coefficient of the image can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to a method for adding a watermark, a device for adding a watermark, and an electronic device for implementing the method for adding a watermark. Background technique [0002] In order to declare the copyright information of the image, a layer of watermark is generally added to the image without affecting the content of the image. [0003] Specifically, mark information (such as patterns, characters, letters, and data, etc.) used to declare the copyright information of the image is used as a watermark, and further, the watermark is added to the image to form an image containing the watermark. [0004] However, the anti-theft coefficient of the watermark adding scheme provided by the related art is low. [0005] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the pre...
