Abstract

The present invention discloses a news video poster picture generation method and apparatus. The method comprises: decomposing a target news video into at least one shot; extracting m frames of key frames of the shot according to a preset time interval; processing each key frame respectively, and generating anchor mark information of the key frame; performing news headline detection on the targetnews video, and generating news headline mark information for marking the key frame based on the start time and end time of the news headline, and the start time point and the end time point of the key frame in the target news video; and based on the anchor mark information of all the key frames and the news headline mark information, generating a poster picture of the target news video.
