Abstract

The embodiment of the invention discloses a watermark detection and video processing method and related equipment. The watermark detection method comprises the steps: detecting a target region for a watermark in original image data; extracting target image features for the watermark from the target image data, the target image data being image data located in the target area in the original imagedata; determining the reference image feature of the reference image data, wherein the reference image data has a watermark for marking a specified category; and comparing the target image feature with the reference image feature to detect the watermark in the category in the original image data. Different types of watermarks can be recalled by configuring the reference image features of differenttypes of watermarks, and the reference image features of the corresponding types of watermarks can be added under the condition that the types of the watermarks are increased so that the flexible expansion of the types of the watermarks is supported.

Description

technical field [0001] The embodiment of the present invention relates to watermark processing technology, in particular to a watermark detection, video processing method and related equipment. Background technique [0002] With the development of the Internet information age, more and more companies, organizations and individuals choose to share images and videos on the Internet. In order to protect copyright, they usually put watermarks on images and videos. [0003] Due to the frequent occurrence of watermarks, in some occasions, corresponding service processing is performed based on the watermarks. At this time, it is necessary to detect the watermarks in images and videos. [0004] The existing watermark detection methods can be divided into the following two categories: [0005] (1), watermark detection method based on manual features [0006] Use the sliding window method, selective search (selective search) and other methods to generate candidate regions, and then ...
