    • A method for personalized video depth adjustment includes receiving a video frame, obtaining a frame depth map based on the video frame, and determining content genre of the video frame by classifying content of the video frame into one or more categories. The method also includes identifying a user viewing the video frame, retrieving depth preference information for the user from a user database, and deriving depth adjustment parameters based on the content genre and the depth preference information for the user. The method further includes adjusting the frame depth map based on the depth adjustment parameters, and providing a 3D video frame for display at a real-time playback rate on a user device of the user. The 3D video frame is generated based on the adjusted frame depth map.
    • 用于个性化视频深度调整的方法包括:接收视频帧,基于视频帧获得帧深度图,以及通过将视频帧的内容分类为一个或多个类别来确定视频帧的内容类型。 该方法还包括识别观看视频帧的用户,从用户数据库检索用户的深度偏好信息,以及基于用户的内容类型和深度偏好信息导出深度调整参数。 该方法还包括基于深度调整参数来调整帧深度图,并且提供用于在用户的用户设备上以实时回放速率显示的3D视频帧。 基于经调整的帧深度图生成3D视频帧。

    • The disclosure is directed to techniques for automatic segmentation of a region-of-interest (ROI) video object from a video sequence. ROI object segmentation enables selected ROI or "foreground" objects of a video sequence that may be of interest to a viewer to be extracted from non-ROI or "background" areas of the video sequence. Examples of a ROI object are a human face or a head and shoulder area of a human body. The disclosed techniques include a hybrid technique that combines ROI feature detection, region segmentation, and background subtraction. In this way, the disclosed techniques may provide accurate foreground object generation and low-complexity extraction of the foreground object from the video sequence. A ROI object segmentation system may implement the techniques described herein. In addition, ROI object segmentation may be useful in a wide range of multimedia applications that utilize video sequences, such as video telephony applications and video surveillance applications.
    • 本公开涉及从视频序列自动分割感兴趣区域(ROI)视频对象的技术。 ROI对象分割使得可以从视频序列的非ROI或“背景”区域中提取观看者感兴趣的视频序列的所选ROI或“前景”对象。 ROI对象的示例是人体的人脸或头肩部区域。 所公开的技术包括组合ROI特征检测,区域分割和背景减除的混合技术。 以这种方式,所公开的技术可以从视频序列提供前景对象生成和前景对象的低复杂度提取的准确性。 ROI对象分割系统可以实现本文描述的技术。 此外,ROI对象分割可能在使用诸如视频电话应用和视频监控应用之类的视频序列的多种多媒体应用中是有用的。

    • This disclosure describes rate control techniques that can improve video coding based on a "two-pass" approach. The first pass codes a video sequence using a first set of quantization parameters (QPs) for the purpose of estimating rate distortion characteristics of the video sequence based on the statistics of the first pass. A second set of QPs can then be defined for a second coding pass. The estimated rate-distortion characteristics of the first pass are used to select QPs for the second pass in a manner that minimizes quality fluctuation between the frames of the video sequence. Furthermore, selection of the second set of QPs may also substantially maximize quality of the frames at the substantially minimized quality fluctuation in order to achieve low average frame distortion with the minimized quality fluctuation.
    • 本公开描述了可以基于“双程”方法改进视频编码的速率控制技术。 第一次通过使用第一组量化参数(QP)编码视频序列,以便基于第一遍的统计来估计视频序列的速率失真特性。 然后可以为第二编码通道定义第二组QP。 第一遍的估计速率 - 失真特性用于以最小化视频序列的帧之间的质量波动的方式来选择第二遍的QP。 此外,第二组QP的选择也可以在基本上最小化的质量波动下基本上最大化帧的质量,以便以最小化的质量波动来实现低平均帧失真。
