Abstract

The invention provides a method and device for obtaining a mark mask in a video, and the method is characterized in that the method comprises the steps: dividing a mark region from a mark frame, wherea mark exists, in the video, wherein the mark region is a part of region which is located at a specific position in a video frame and contains the mark; determining a video frame used for extractinga mark mask in the video frames of the video; superposing and strengthening the marked edge of the marked area of the video frame for extracting the marked mask to obtain an image of the marked area containing the strengthened edge information; acquiring a marker mask in the video based on an image of a marker region containing enhanced edge information. According to the method and the device forobtaining the mark mask, the accurate mark mask can be extracted, the construction of a huge mark database for template matching is avoided, and the calculation amount of subsequent mark removal can be reduced.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet, and in particular to a method, a device, and a computer-readable storage medium for acquiring a marker mask in a video. Background technique [0002] With the rapid development of major video platforms and the self-media industry in recent years, many people have gradually become accustomed to using videos to record and share their daily life, thus generating more and more demands for post-processing of videos, including removing Various marks, such as watermarks or station logos added to videos by video producers or video platforms.
