Abstract

The invention discloses a method for adding a watermark into a picture. The method is executed in computation equipment. The method comprises the following steps: partitioning a target picture into a plurality of regions; specific to each region of the plurality of regions, computing the information entropy of the region based on the color value of each pixel point in the region; selecting a region with a minimum information entropy from the plurality of regions for serving as a target region, and adding a watermark picture into the target region of the target picture. The invention further discloses a device for adding the watermark into the picture and the computation equipment comprising the device.

Description

technical field [0001] The invention relates to the fields of computers and the Internet, in particular to a method, device and computing equipment for adding watermarks to pictures. Background technique [0002] In the current Internet age, pictures are the easiest and most convenient source of information to be accepted by people. For the purpose of promoting and protecting copyrights, various websites often add their own unique watermarks to webpage pictures, for example, adding watermarks with website names or URLs to pictures. If the watermark is added in an inappropriate position, it will destroy the visual effect of the original picture and affect the dissemination of the information of the picture itself. Therefore, when adding a watermark to a picture, how to determine the adding position of the watermark is particularly important. [0003] In the prior art, the best position to add the watermark in the picture is generally determined manually through visual recog...
