Video cropping method and device, equipment and storage medium

Abstract

The invention provides a video cropping method and device, equipment and a storage medium. The method comprises the following steps: acquiring at least one detection box of a first image frame; determining the cost of the detection box according to at least one selected from the importance score, the coverage area and the smooth distance of any detection box in the at least one detection box; determining the first detection box with the lowest cost in the at least one detection box as a cropping box; and cropping a first image frame based on the cropping frame. Based on the cost of each detection frame, the first detection frame with the minimum cost in the at least one detection frame is determined as the cropping frame so as to crop the first image frame, thereby improving the flexibility of video cropping and enhancing the cropping effect under the condition of ensuring the simplification of a video cropping process.

Description

technical field

[0001] The embodiments of the present application relate to the field of computer vision, and more specifically, to a method, device, device and storage medium for cropping a video. Background technique

[0002] Usually, the aspect ratio of the ad space used to place the advertising video is fixed, such as 9:16. However, the size of the original video is various, for example, different original videos have different aspect ratios, so , causing many original videos to be inconsistent with the size required by the ad slot, making it impossible to directly place original videos of other sizes on the ad slot. Based on this, the original video needs to be cropped to fit the size of the ad slot.

[0003] So far, the original video is generally cropped by center cropping.

[0004] However, due to the randomness of the position of important information in the original video, cutting the original video by means of center cropping may cause the important information ...
