演示视频的增强分割和可视化
Augmented Segmentation and Visualization for Presentation Videos
摘要：
我们调查的分割，可视化和索引演示视频分别考虑音频和视觉数据的方法。音轨由扬声器分段，并使用自动语音识别器（ASR）提取的关键短语进行增强。视频轨迹被分割的视觉相异和增强的代表性的关键帧。交互式用户界面组合了音频、视频、文本和关键帧的视觉表示，并允许用户导航演示视频。我们还探讨了说话人数据的聚类和标记，并提出了初步的结果。
英文摘要：
We investigate methods of segmenting, visualizing, and indexing presentation videos by separately considering audio and visual data. The audio track is segmented by speaker, and augmented with key phrases which are extracted using an Automatic Speech Recognizer (ASR). The video track is segmented by visual dissimilarities and augmented by representative key frames. An interactive user interface combines a visual representation of audio, video, text, and key frames, and allows the user to navigate a presentation video. We also explore clustering and labeling of speaker data and present preliminary results.
