Abstract

The invention discloses a video concentration method and device, and relates to the technical field of computers, in particular to the technical field of artificial intelligence, one specific embodiment comprises the steps of obtaining a to-be-concentrated video, and determining a target video frame in the to-be-concentrated video; determining the pixel point area of a foreground mask corresponding to the next frame of the target video frame, and dividing the video scene of the to-be-concentrated video based on the pixel point area and a preset threshold value; and allocating a track to each video scene based on the time sequence, and fusing each video scene based on the allocated track to generate a concentrated video. Therefore, the video scenes are divided by judging whether the pixel point area of the foreground in the foreground mask is smaller than the preset threshold value or not, and the video scenes are fused based on the allocated tracks by allocating the tracks to the divided video scenes, so that the video concentration efficiency is improved, and the video concentration quality is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of artificial intelligence technology, and in particular to a video concentration method and device. Background technique [0002] At present, when video is concentrated, it is usually based on the method of foreground and background separation. By judging whether the foreground is still, the foreground is divided into a stop state and a motion state, and then the part of the video in the stop state is deleted to achieve the effect of concentrating the video. This will result in low video enrichment efficiency and low video enrichment quality. [0003] During the process of implementing this application, the inventors found that at least the following problems existed in the prior art: [0004] The efficiency of video concentration is low, and the quality of video concentration is not high. Contents of the invention [0005] In view of this, the embodime...
