Embodiment 1

[0045] figure 1 It is a flow chart of steps in an embodiment of a video mask special effect processing method of the present invention.

[0046] refer to figure 1 As shown, the masking special effect processing method provided by this embodiment is applied to a video editing system, and the video editing system is used to perform linear or non-linear editing processing on the video material to be edited to obtain the final effect required by the user. The masking special effect The processing method specifically includes the following steps:

[0047] S101: Determine a mask area of ​​a first frame image of a video.

[0048] The video is the video data of the mask object to be added. When the mask special effect processing needs to be performed on the video, the mask area where the mask object to be added to the video is located is determined according to the predetermined mask special effect target. .

[0049] The specific determination steps include: first adding the video...

Embodiment 2

[0062] figure 2 It is a structural block diagram of an embodiment of a video mask special effect processing device of the present invention.

[0063] refer to figure 2 As shown, the mask special effect processing device provided by this embodiment is applied to a video editing system, and the video editing system is used to perform linear or non-linear editing processing on the video material to be edited to obtain the final effect required by the user. The mask special effect The processing device specifically includes an area determination module 10 , a feature point determination module 20 , a tracking processing module 30 and a mask processing module 40 .

[0064] The area determination module 10 is used to determine the mask area of ​​the first frame image of the video.

[0065] The video is the video data of the mask object to be added. When the mask special effect processing needs to be performed on the video, the mask area where the mask object to be added to the v...

Abstract

The invention provides a video shade trick processing method and a video shade trick processing device. The video shade trick processing method and device are applied to a video editing system. The method specifically comprises the steps of determining a shade area of a first frame of a video to which a shade object is to be added according to a preset shade trick target; determining a plurality of feature points forming the shade area of the first frame; tracking each frame from the first frame, and determining the shade area of each frame according to variation of the feature points during a tracking process; and sequentially adding the shade objects into the shade areas of all frames during the tracking process. Therefore, tracking on the variation of the shade area is achieved by a way of tracking variation of the feature points, so that the shade area varies according to the variation of a location of a shaded object, and thus the shade object can always cover the shaded object, and the shade trick effect is improved.

Description

technical field [0001] The invention relates to the technical field of video editing, in particular to a video mask special effect processing method and a video mask special effect processing device. Background technique [0002] In the video editing system, some special visual effects can be achieved by adding video special effects, thus making the video content more abundant. Among them, the masking effect is a commonly used special effect method. By setting a specific area of ​​the mask, the objects in the specific area are made invisible; or a part of a certain component is masked to achieve some special effects. Generally speaking, the conventional mask area will be fixed, and the mask processing is relatively simple; however, when the object to be masked moves, the mask object cannot move with the object, so that the mask object cannot always be masked in this area. On moving objects, the masking effect is poor. Contents of the invention [0003] In view of this, t...
