Title (EN) VIDEO ABSTRACT GENERATING METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF DE PRODUCTION D'EXTRAIT VIDÉO
(ZH) 视频摘要生成方法及装置
Abstract:
(EN) Disclosed in the invention are a video abstract generating method and device. The method comprises the following steps: obtaining a video to be processed; dividing the video to be processed into a plurality of slices; starting a plurality of threads in one-to-one correspondence to the plurality of slices, and respectively performing a target analysis task on each slice to obtain an analysis result of a moving target in each slice; and carrying out concentration calculation on the analysis results of the moving targets based on a sequential order of the plurality of slices to generate a video abstract of the video to be processed. According to the video abstract generating method provided by embodiments of the invention, by processing target analysis tasks of a video by using multiple threads in parallel and then carrying out integrated concentration on the dispersed analysis results to generate a video abstract, an objective of browsing all contents of the video within a short time is achieved and thus waiting time is significantly reduced.
(FR) La présente invention concerne un procédé et un dispositif de production d'un extrait vidéo. Le procédé comprend les étapes suivantes consistant à : obtenir une vidéo à traiter ; diviser la vidéo à traiter en une pluralité de segments ; démarrer une pluralité de fils en correspondance biunivoque avec la pluralité de segments et exécuter respectivement une tâche d'analyse cible sur chaque segment pour obtenir un résultat d'analyse d'une cible mobile dans chaque segment ; et effectuer un calcul de concentration sur les résultats d'analyse des cibles mobiles sur la base d'un ordre séquentiel de la pluralité de segments pour produire un extrait vidéo de la vidéo à traiter. Selon le procédé de production d'extrait vidéo fourni par des modes de réalisation de l'invention, en traitant des tâches d'analyse cibles d'une vidéo à l'aide de multiples fils en parallèle, puis en effectuant une concentration intégrée sur les résultats d'analyse dispersés pour produire un extrait vidéo, un objectif de navigation de tout le contenu de la vidéo dans un court laps de temps est obtenu et, par conséquent, le temps d'attente est significativement réduit.
(ZH) 本发明公开了一种视频摘要生成方法及装置,其中,方法包括以下步骤:获取待处理视频;将所述待处理视频划分为多个切片;开启与所述多个切片一一对应的多个线程,分别执行对每个所述切片的目标分析任务,得到每个所述切片中运动目标的分析结果;利用所述多个切片的先后顺序对所述运动目标的分析结果进行浓缩计算,以生成所述待处理视频的视频摘要。本发明实施例提供的视频摘要生成方法,通过使用多线程并行处理一个视频的目标分析任务,然后对于分散的分析结果进行综合浓缩,生成视频摘要,以实现在短时间内浏览视频所有内容的目的,从而极大减少了等待时间。
