Abstract: A video segmentation system can be utilized to automate segmentation of digital video content. Features corresponding to visual, audio, and/or textual content of the video can be extracted from frames of the video. The extracted features of adjacent frames are compared according to a similarity measure to determine boundaries of a first set of shots or video segments distinguished by abrupt transitions. The first set of shots is analyzed according to certain heuristics to recognize a second set of shots distinguished by gradual transitions. Key frames can be extracted from the first and second set of shots, and the key frames can be used by the video segmentation system to group the first and second set of shots by scene. Additional processing can be performed to associate metadata, such as names of actors or titles of songs, with the detected scenes.

Abstract translation: 可以利用视频分割系统来自动分割数字视频内容。 可以从视频的帧中提取与视频的视觉，音频和/或文本内容相对应的特征。 根据相似性度量来比较相邻帧的提取特征，以确定通过突变转换区分的第一组镜头或视频片段的边界。 根据某些启发式分析第一组镜头，以识别通过逐渐转换区分的第二组镜头。 可以从第一和第二组拍摄中提取关键帧，并且关键帧可以被视频分割系统用于按照场景对第一组和第二组拍摄进行分组。 可以执行附加处理以将元数据（例如演员的名称或歌曲的名称）与检测到的场景相关联。

Abstract: Automatic replay or skip ahead functionality can be configured to intelligently navigate to a portion of a video a user desires to view. The context at which a user selects intelligent navigation can be analyzed to determine where to initiate automatic replay or skip ahead. The context for intelligent navigation can be based on scene or shot segmentation data, closed captioning, aggregate video navigation data from a community of users of shared demographic traits and/or interest, and/or other metadata. In the case of automatic replay, playback of a portion of a video can include enhancements for that portion, such as providing closed captioning, display at a decreased frame rate (“slow motion”), zooming in/out on a portion of the frames of a video segment, among other enhancements.
