摘要： A wide spread adoption of 3D videos and technologies is hindered by the lack of high-quality 3D content. One promising solution to address this problem is to use automated 2D-to-3D conversion. However, current conversion methods, while general, produce low-quality results with artefacts that are not acceptable to many viewers. Creating a database of 3D stereoscopic videos with accurate depth is, however, very difficult. Computer generated content can be used to generate high-quality 3D video reference database for 2D-to-3D conversion. The method transfers depth information from frames in the 3D reference database to the target frame while respecting object boundaries. It computes depth maps from the depth gradients, and outputs a stereoscopic video.

摘要： A computer-implemented method comprises of processing data for a source video to determine representative topics of the video, determining multiple topics of interest for respective ones of multiple market segments, using the representative topics and the multiple topics to determine a target audience for the video from the market segments, using the topics of interest for the target audience to determine a set of keywords for an advertisement, using the set of keywords to provide multiple candidate advertisements for the target audience, generating a ranked list from the multiple candidate advertisements, and selecting an advertisement for the source video from the ranked list of candidate advertisements.
摘要翻译：计算机实现的方法包括处理源视频的数据以确定视频的代表性主题，使用代表主题和多个主题来确定视频的目标受众以确定多个细分市场中的相应多个细分市场的多个主题从市场部分，使用目标受众感兴趣的主题来确定广告的一组关键字，使用该组关键字为目标受众提供多个候选广告，从多个候选广告中生成排名列表，以及从候选广告的排名列表中选择源视频的广告。

摘要： A method for detecting whether query video data appears in a reference video, comprising determining a measure of depth from a portion of the query video data, comparing the measure against a measure of depth for the reference video to perform a depth match and, if a match is determined; comparing a visual signature derived from the query video data against a visual signature of the reference video to perform a visual match to determine a measure representing the likelihood that the query video data derives from the reference video.
摘要翻译：一种用于检测查询视频数据是否出现在参考视频中的方法，包括从所述查询视频数据的一部分确定深度测量值，将所述测量与所述参考视频的深度测量值进行比较以执行深度匹配;以及如果比赛确定; 将从查询视频数据导出的视觉签名与参考视频的视觉签名进行比较，以执行视觉匹配，以确定表示查询视频数据从参考视频派生的可能性的度量。
