| Popis: | 100 When we watch videos with video discs like DVDs or VCDs, we can only watch by chapters. We cannot do some search on the content of video. So we provide a retrieval system for video subtitles, and hopefully do some progress on searching the video content. NTU Literary Lecture Series published by National Taiwan University Press are videos of speech giving by some modern literature writers in Taiwan. There are videos on DVDs and a speech manual for every video in NTU Literary Lecture Sreies. People may read speech manuals to scan the content of videos quickly. When people find a interesting paragraph and want to watch the part of video, they cannot easily do that. To solve this problem, we create the subtitle files of videos by esrXP which captures pictures of subtitles and Microsoft Office Document Imaging which does OCR on pictures to get the text of subtitles. Additionally, we match subtitles to the sentences in speech manual for giving more information to users. Then we access videos through web. By using video tag of HTML5 on webpage, users can easily watch the videos without any plug-in if they use HTML5-supported browsers like Google Chrome and Mozilla Firefox. When users watch videos, the sentences correspond to the subtitle will be displayed below the player. It will provide more information to users on selecting subtitles. We also provide the function of post-classification to users for filtering the retrieval results. |
