摘要： A decoder may apply a resource-focused interpolation mode to enable or disable interpolation or extrapolation of video units, such as frames, based on power and quality considerations. In one mode, interpolation may be disabled to conserve power when reference frames are not likely to produce satisfactory quality. In another mode, the threshold may be adjustable as a function of power saving requirements. This disclosure also describes selection of reference video frames to be used for interpolation or extrapolation of a video frame. A decoder may apply a quality-focused mode to select a reference frame based on quality criteria. The quality criteria may indicate a level of quality likely to be produced by a reference frame. If no reference frames satisfy the quality criteria, interpolation or extrapolation may be disabled. Display of an interpolated or extrapolated frame may be selectively enabled based on a quality analysis of the frame.

摘要： This disclosure is directed to techniques for selective video frame rate upconversion (FRUC) in a video decoder. A video decoder selectively enables or disables FRUC based on one or more adaptive criteria. The adaptive criteria may be selected to indicate whether FRUC is likely to introduce spatial artifacts. Adaptive criteria may include a motion activity threshold, a mode decision threshold, or both. The criteria are adaptive, rather than fixed. When the criteria indicate that a frame includes excessive motion or new content, the decoder disables FRUC.
摘要翻译：本公开涉及视频解码器中用于选择性视频帧速率上变频（FRUC）的技术。视频解码器基于一个或多个自适应标准选择性地启用或禁用FRUC。可以选择适应性标准来指示FRUC是否可能引入空间伪像。自适应标准可以包括运动活动阈值，模式判定阈值或两者。标准是适应性的，而不是固定的。当标准表示帧包含过多运动或新内容时，解码器禁用FRUC。

摘要： The disclosure is directed to decoder-side region-of-interest (ROI) video processing. A video decoder determines whether ROI assistance information is available. If not, the decoder defaults to decoder-side ROI processing. The decoder-side ROI processing may estimate the reliability of ROI extraction in the bitstream domain. If ROI reliability is favorable, the decoder applies bitstream domain ROI extraction. If ROI reliability is unfavorable, the decoder applies pixel domain ROI extraction. The decoder may apply different ROI extraction processes for intra-coded (I) and inter-coded (P or B) data. The decoder may use color-based ROI generation for intra-coded data, and coded block pattern (CBP)-based ROI generation for inter-coded data. ROI refinement may involve shape-based refinement for intra-coded data, and motion- and color-based refinement for inter-coded data.
摘要翻译：本公开涉及解码器侧感兴趣区域（ROI）视频处理。视频解码器确定ROI辅助信息是否可用。如果不是，则解码器默认为解码器侧ROI处理。解码器侧ROI处理可以估计比特流域中的ROI提取的可靠性。如果ROI可靠性较好，则解码器应用比特流域ROI提取。如果ROI可靠性不利，则解码器应用像素域ROI提取。解码器可以对帧内编码（I）和帧间编码（P或B）数据应用不同的ROI提取处理。解码器可以使用用于帧内编码数据的基于颜色的ROI生成，以及用于帧间编码数据的基于编码块模式（CBP）的ROI生成。 ROI细化可能涉及帧内编码数据的基于形状的细化，以及帧间编码数据的基于运动和颜色的细化。

摘要： 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.

摘要： The disclosure relates to techniques for video source rate control for video telephony (VT) applications. The source video encoding rate may controlled using a dual-buffer based estimation of a frame budget that defines a number of encoding bits available for a frame of the video. The dual-buffer based estimation technique may track the fullness of a physical video buffer and the fullness of the virtual video buffer. The source video encoding rate is then controlled based on the resulting frame budget. The contents of the virtual buffer depend on constraints imposed by a target encoding rate, while the contents of the physical buffer depend on constraints imposed by varying channel conditions. Consideration of physical video buffer fullness permits the video source rate control technique to be channel-adaptive. Consideration of virtual video buffer fullness permits the video source rate control technique to avoid encoding excessive video that could overwhelm the channel.
摘要翻译：本公开涉及用于视频电话（VT）应用的视频源速率控制的技术。源视频编码速率可以使用帧预算的基于双缓冲器的估计来控制，该帧预算定义可用于视频的帧的编码比特的数量。基于双缓冲器的估计技术可以追踪物理视频缓冲器的充满度和虚拟视频缓冲器的充满度。然后根据所得到的帧预算来控制源视频编码速率。虚拟缓冲区的内容取决于目标编码速率施加的约束，而物理缓冲区的内容取决于由变化的信道条件施加的约束。考虑物理视频缓冲器充满度允许视频源速率控制技术具有通道适应性。考虑虚拟视频缓冲器的充满度允许视频源码率控制技术避免编码可能压倒频道的过多视频。
