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： This disclosure describes adaptive filtering techniques to improve the quality of captured imagery, such as video or still images. In particular, this disclosure describes adaptive filtering techniques that filter each pixel as a function of a set of surrounding pixels. An adaptive image filter may compare image information associated with a pixel of interest to image information associated with a set of surrounding pixels by, for example, computing differences between the image information associated with the pixel of interest and each of the surrounding pixels of the set. The computed differences can be used in a variety of ways to filter image information of the pixel of interest. In some embodiments, for example, the adaptive image filter may include both a low pass component and high pass component that adjust as a function of the computed differences.

摘要： A stereo 3D video frame includes left and right components that are combined to produce a stereo image. For a given amount of distortion, the left and right components may have different impacts on perceptual visual quality of the stereo image due to asymmetry in the distortion response of the human eye. A 3D video encoder adjusts an allocation of coding bits between left and right components of the 3D video based on a frame-level bit budget and a weighting between the left and right components. The video encoder may generate the bit allocation in the rho (ρ) domain. The weighted bit allocation may be derived based on a quality metric that indicates overall quality produced by the left and right components. The weighted bit allocation compensates for the asymmetric distortion response to reduce overall perceptual distortion in the stereo image and thereby enhance or maintain visual quality.
摘要翻译：立体3D视频帧包括组合以产生立体图像的左和右组件。对于给定量的失真，由于人眼的失真响应的不对称，左和右分量可能对立体图像的感知视觉质量具有不同的影响。 3D视频编码器基于帧级比特预算和左右分量之间的加权来调整3D视频的左和右分量之间的编码比特的分配。视频编码器可以在rho（rho）域中生成比特分配。可以基于指示左组件和右组件产生的总体质量的质量度量来导出加权比特分配。加权比特分配补偿非对称失真响应，以减少立体图像中的整体感知失真，从而增强或维持视觉质量。

摘要： Techniques are presented herein to provide tandem-free operation between two wireless terminals through two otherwise incompatible wireless networks. Specifically, embodiments provide tandem-free operation between a wireless terminal communicating through a continuous transmission (CTX) wireless channel to a wireless terminal communicating through a discontinuous transmission (DTX) wireless channel. In a first aspect, inactive speech frames are translated between DTX and CTX formats. In a second aspect, each wireless terminal includes an active speech decoder that is compatible with the active speech encoder on the opposite end of the mobile-to-mobile connection.

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。
