Embodiment Construction
[0050] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0051] The embodiment of the present invention provides a method for editing video based on emotional curves. The emotional curve is determined by collecting the user's expression when watching the video, and then the climax part of the target video is determined according to the emotional curve, so as to quickly locate the editing position. Specifically, see figure 1 As shown, the method for clipping video includes steps 101-104:
[0052] Step 101: Obtain multiple facial expression videos of multiple users collected when the target video is played, and determine multiple facial expression images including time stamps according to each facial expression video.

The present invention provides a method and device for editing videos based on emotional curves, wherein the method includes: acquiring multiple facial expression videos of multiple users collected when playing the target video, and determining multiple facial expression videos containing time stamps respectively Facial expression image; face expression recognition processing is performed on the facial expression image, the characteristic value of the human facial expression is determined, and the corresponding emotional value group is determined; the emotional value in the multiple emotional value groups corresponding to the same time stamp is respectively Mean value processing, determine the final emotional value group, and determine the emotional curve group corresponding to the target video according to the final emotional value group fitting of different time stamps; determine the corresponding target video according to the peak or trough of the emotional curve in the emotional curve group , and determine the clipping range of the target video according to the position of the key frame. This method uses key frames to quickly locate the editing position, which can greatly improve the efficiency of editing operations.
Description
technical field [0001] The invention relates to the technical field of video editing, in particular to a method and device for editing video based on emotional curves. Background technique [0002] At present, when users are editing videos, they sometimes need to edit out the funniest, most sensational, or most frightening parts of the video, because people’s time is limited, and the speed at which people process video information is also limited. There are limitations, so users cannot watch all the videos from beginning to end, so often for a video editor or a user in a similar position, choosing where to edit the video is often a very challenging task, time-consuming Laborious and inefficient. [0003] One of the existing solutions is to provide a fast-forward function to allow users to quickly watch the video. But even at a speed of 3 times, the user still needs to spend time, and it will waste a lot of energy of the user to watch this video, and the user is easily fati...
