Abstract

The invention proposes a video preview generation method, device, server and system. The method comprises the following steps: receiving a video previewing request; obtaining a video list corresponding to the video previewing request; obtaining a video snapshot set of a video in the video list; inputting the video snapshot set into a two-class depth neural network model, and obtaining a probability result outputted by the model; carrying out the selection of video snapshots in the video snapshot set according to the probability result and determining a video preview.

Description

technical field [0001] The invention belongs to the field of computer image processing, and in particular relates to a video preview generation method, device, server and system. Background technique [0002] When a user watches a video on the Internet, if he does not know the relevant situation of the video, he wants to know the general content of the video through a preview method, so as to decide whether to continue watching. In this case, users often learn about a video by continuously dragging at will. This kind of dragging is very random. In most cases, the position that the user drags is not necessarily the key part of the entire video. Users can quickly understand the content of the entire video to a limited extent. Therefore, in this case, the user urgently needs a function that automatically generates a movie trailer, and provides the user with a fast movie content preview function, that is, a video preview image. [0003] At present, video preview images are mos...
