Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the specific details of the present invention described below are only for illustrating the present invention, and do not constitute a limitation to the present invention. Any modifications and variations made in accordance with the teachings of the invention as described are also within the scope of the invention.

[0046] We know that video is made up of image frames, and in the present invention, we assume that the relative position of the defaced area (unknown area) in each picture frame in the video frame is fixed (as, the station logo position in the video are fixed), assuming that the defaced area in each picture frame is circular, then the defaced area in all picture frames in the video forms a columnar hole to be filled, such as figure 2 As shown in , the white circular area is the defaced area to be f...

Abstract

The invention belongs to the technical field of multimedia information, and discloses a method for filling corrupted areas in a video. The filling method comprises the following steps: S1, performing calculation to obtain filling priorities of all boundary points between an unknown area and a known area in a picture frame of the video; S2, taking a point with a highest filling priority as a center to obtain a first video block, and finding a second video block having a highest similarity to the first video block in the known areas of the video; S3, filling the first video block based on the second video block; S4, updating boundary points of the unknown areas and the known areas in the video; and S5, repeating the step S1 to the step S4 till the unknown areas in all picture frames in the video are filled. Through adoption of the method, a user does not view boundaries of filled areas during playing of the filled video, and meanwhile a flashing phenomenon occurring in the filled areas is eliminated.

Description

technical field [0001] The invention belongs to the technical field of multimedia information, and in particular relates to a method for filling a defaced area in a video. Background technique [0002] Common video defacement is generally caused by information insertion, and it is more common to insert copyright information into the video. figure 1 Shown is a frame intercepted from the video. It can be seen from the figure that there are 3 insertions in the video, that is, three defacements. Channel logo), the upper right corner is "CNTV HD" (the logo of China Internet TV HD channel), and the lower right corner is the M-shaped logo of "Movie Channel". [0003] At present, there are many methods to solve video defacement, such as blurring or mosaic filling the area of ​​the station logo. Although this method makes the user unable to see the original station logo, it greatly reduces the viewing value of the video. Another example is to use the method of image texture synthes...
