Embodiment 1

[0058] figure 1 It is a flow chart of the video picture splicing method provided by Embodiment 1 of the present invention. The embodiment illustrates how to splice video frames of a video file. Such as figure 1 As shown, the method specifically includes the following steps:

[0059] 101: Obtain multiple video frames from a video file.

[0060] Each frame of video picture can be obtained from the video file. For example, if the length of the video file is 1 minute and there are 24 frames of images per second, then 24*60=1440 video frames are acquired.

[0061] It is also possible to obtain video frames from the video file at preset time intervals. For example, the length of the video file is 1 minute, and if one video frame is acquired every second, then 60 video frames are acquired. Because subtitles in the video do not change too quickly, a certain time interval will not cause data omission, so obtaining video images from the video file at preset time intervals can ensu...

Embodiment 2

[0080] The video picture splicing method of Embodiment 2 acquires a plurality of video pictures from a video file, and identifies video pictures with different subtitles from the plurality of video pictures, and when the similarity between the video pictures with different subtitles is less than a specified value , directly splicing the different video frames of the subtitles, when the similarity between the different video frames of the subtitles is not less than a specified value, intercept the subtitle area from the different video frames of the subtitles, and perform Splicing, so as to realize the splicing of video images of different subtitles in the video according to the similarity of the video images, and reduce data redundancy, which is convenient for users to view and share subtitles in the video.

Embodiment 3

[0082] Figure 6 It is a structural diagram of a video picture splicing device provided by Embodiment 3 of the present invention. Such as Figure 6 As shown, the video picture splicing device 10 may include: an acquisition unit 601 , an identification unit 602 and a splicing unit 603 .

[0083] An acquiring unit 601, configured to acquire multiple video frames from a video file.

[0084] The obtaining unit 601 may obtain each video frame from the video file. For example, if the length of the video file is 1 minute and there are 24 frames of images per second, then 24*60=1440 video frames are obtained.

[0085] The obtaining unit 601 may also obtain video frames from the video file at preset time intervals. For example, the length of the video file is 1 minute, and if one video frame is acquired every second, then 60 video frames are acquired. Because subtitles in the video do not change too quickly, a certain time interval will not cause data omission, so obtaining video ...

Abstract

The invention provides a video image stitching method. The method comprises the following steps: obtaining a plurality of video images from a video file; identifying video images, the subtitles of which are different, from the plurality of video images, wherein the subtitle of the video image obtained through next identification is different from that of the video image obtained through the previous identification in the video images, the subtitles of which are different; and carrying out image stitching on the video images, the subtitles of which are different. The invention also provides a video image stitching device. The method and device can device can realize image stitching of the video images, the subtitles of which are different, to facilitate a user to check and share the subtitles in the video.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for splicing video images. Background technique [0002] At present, mobile terminals (such as mobile phones) are more and more widely used. When a user watches a video, he sometimes wishes to splice together pictures of different subtitles in the video. Existing methods usually need to manually capture video images, and then use image editing software to stitch them together, which takes a lot of time and is inconvenient, and it is not convenient for users to view and share the subtitles in the video. Contents of the invention [0003] In view of the above, it is necessary to propose a method for splicing video images, which can splice video images with different subtitles in the video, so as to facilitate users to view and share the subtitles in the video. [0004] The first aspect of the present application provides a method for splicing video images, the...
