Abstract

The invention provides a clipping method, system and device for a transverse and vertical screen conversion picture and a storage medium, and the method comprises the following steps: obtaining a transverse screen audio and video file, and separating the transverse screen audio and video file to obtain a video picture and an audio file; obtaining a face position in the video picture, determining a face image, and segmenting the face image to obtain dynamic information; and matching with the audio file according to the dynamic information, and determining a key character according to a matching result. According to the method, a video picture and an audio file are separated, dynamic information of a human face is segmented in the video picture, feature matching is carried out on the dynamic information obtained through segmentation and the audio file so as to locate speakers in the video, key figures and non-key figures are distinguished on a section of video containing a multi-person picture, therefore, the image of the key figure can be reserved as much as possible while the image of the non-key figure can be clipped to obtain a better clipping effect, and the method can be widely applied to the technical field of video processing.

Description

Technical field [0001] The present invention relates to the field of video processing, in particular a cropping method, system, device, and storage medium of a horizontal and vertical screen conversion screen. Background technique [0002] Among the video products, there are two different video forms: horizontal video and vertical video. Overall, the content of the horizontal video is more rich and more content, because of its length, ordinary users are used to watching mobile phones to watch to get better viewing experience; and the vertical video is more interesting, The time is short, and the plot is more focused and concise. In a more fragmented time and scene, the user is usually more inclined to watch in the sharing screen. When any processing is not performed, the video screen is scaled directly, and the vertical video is displayed in the horizontal screen or the horizontal video will appear in the vertical screen. There will be a large number of black sides. [0003] At p...
