Abstract

The invention relates to a video cropping method and device, a storage medium and electronic equipment, so as to achieve the purpose of dynamically adjusting the size of a corresponding cropping frameaccording to main body contents in different target video frames, retain most main body contents of each frame of picture in an original video, and improve the quality of cropped videos. The video cropping method comprises the steps of obtaining a to-be-cropped original video; performing frame extraction on the original video to obtain a plurality of target video frames; for each target video frame, determining a target candidate cutting box corresponding to the target video frame according to the main body content in the target video frame; performing interpolation according to the target candidate clipping frame corresponding to each target video frame to determine a target clipping frame corresponding to each frame of picture in the original video; and clipping the original video according to the target clipping frame corresponding to each frame of picture.

Description

technical field [0001] The present disclosure relates to the technical field of video processing, and in particular, to a video cropping method, device, storage medium and electronic equipment. Background technique [0002] Video intelligent cropping is a technology required for scenarios where the video playback size is inconsistent with the original video. The video intelligent cropping algorithm in the related art usually uses a cropping frame of the same size to crop each frame in the video, and then reassembles each cropped frame into a video. However, the content information contained in each frame of the video may be quite different. If you use a cropping frame of the same size to crop each frame, it may cause the loss of most of the frame content and affect the quality of the cropped video. Contents of the invention [0003] This Summary is provided to introduce a simplified form of concepts that are described in detail later in the Detailed Description. This sum...
