Abstract

The invention discloses a video watermark adding method and apparatus. The method comprises the steps of determining a watermark area of each frame of video image in a to-be-added watermark video; calculating the image complexity of the watermark area of each frame of video image; according to the image complexity of the two continuous frames of video images, calculating a gray difference value ofthe two continuous frames of video images; and after obtaining a pre-stored watermark to be added from a memory DC, processing the watermark to be added of two continuous frames of video images basedon the gray difference value of the two continuous frames of video images, and adding the processed watermark to be added to the watermark area of the corresponding video image to obtain a watermark-added video, the problems that according to an existing video watermark adding method, a complete watermark is directly added at a fixed position, and the watermark is easily and directly deducted orsimply replaced by a color block; and the watermark image added with the watermark in the video is relatively prominent, so that the visual effect is influenced are solved.

Description

technical field [0001] The present application relates to the field of multimedia technology, in particular to a video watermark adding method and device. Background technique [0002] Watermark refers to the addition of certain digital or text information in data multimedia (such as video, documents, photos, etc.) to achieve the functions of document authenticity identification and copyright protection. At present, there are various methods for adding video watermarks, but all of them have certain deficiencies. The existing watermarking method is to directly add a complete watermark at a fixed position, which is easy to be deducted directly or simply replaced with a color block; and the watermark image after adding the watermark in the video is more prominent, affecting the visual effect. Contents of the invention [0003] This application provides a video watermark adding method and device, which is used to solve the problem that the existing video watermark adding meth...
