Abstract

The invention provides a video processing method and device, electronic equipment and a storage medium, and belongs to the technical field of videos. In the invention, a first cutting parameter sequence of a target image in a to-be-cut video and a second cutting parameter sequence of a previous frame of image of the target image are acquired; and if a first difference value between the first clipping parameter sequence and the second clipping parameter sequence exceeds a preset difference value range, determining at least one frame of image located behind the target image in the to-be-clipped video as a transition image of the target image. According to the first difference value, performing parameter smoothing on the first cutting parameter sequence to determine a third cutting parameter sequence; wherein the second difference values between the parameters in each third cutting parameter sequence and the parameters in the second cutting parameter sequence are different, and the maximum second difference value is smaller than or equal to the first difference value. And performing object cutting on the target image and the transition image based on the third cutting parameter sequence. In this way, the object cutting shaking problem can be avoided to a certain extent, and the cutting effect is ensured.

Description

technical field [0001] The present disclosure belongs to the field of video technology, and in particular relates to a video processing method, device, electronic equipment and storage medium. Background technique [0002] At present, in the field of video processing, it is often necessary to crop out the objects contained in the image in the video. For example, it is necessary to crop out the faces contained in each frame image contained in the video. [0003] In related technologies, it is often to first calculate the cropping parameter sequence of each frame of image, and then directly crop each frame of image based on the calculated cropping parameter sequence. In this method, affected by factors such as ambient light, image quality, and the robustness of the cropping parameter sequence calculation method itself, the object cropping result of the video will jitter, and the cropping effect is poor. Contents of the invention [0004] In order to overcome the problems e...
