The present invention provides a cutting method, system, device, and storage medium for a horizontal-to-vertical screen conversion picture, the method includes the following steps: acquiring a horizontal-screen audio-visual file, and separating a video image and an audio file from the horizontal-screen audio-visual file; acquiring the video image in the video image The position of the face, determine the face image, and segment the face image to obtain dynamic information; match the dynamic information with the audio file, and determine the key person according to the matching result; the method separates the video image and the audio file, in the video image through Segment the dynamic information of the face, and match the segmented dynamic information with the audio file to locate the speaker in the video, and distinguish the key person from the non-key person in a video containing multi-person images, so that Keep the pictures of key figures as much as possible and crop the pictures of non-key figures to obtain better cropping effect, which can be widely used in the field of video processing technology.
Description
technical field [0001] The present invention relates to the technical field of video processing, in particular to a method, system, device and storage medium for cropping images converted from horizontal to vertical screens. Background technique [0002] In video products, there are two distinct video formats: horizontal video and vertical video. Generally speaking, the horizontal version of the video has richer content and more types of content. Because of the length of time, ordinary users are accustomed to watching the mobile phone horizontally to obtain a better viewing experience; while the vertical version of the video is more interesting, The time is shorter, the plot is more focused and concise. In relatively fragmented time and scenes, users usually prefer to watch in vertical screen. Without any processing, the video screen is directly scaled, and a vertical version of the video is displayed in the landscape state or a horizontal version of the video is displayed...
