摘要： This disclosure describes selective deblock filtering techniques that are particularly useful with coding standards that do not specify in-loop deblock filtering for standard compliance. In accordance with this disclosure, deblock filtering may be selectively performed with respect to block boundaries of a given video block being coded, a motion compensation process can be performed using a filtered version of the prediction video frame used to code the given video block, or both. This disclosure also provides selection rules that can be applied to determine what type of deblocking techniques to apply in various scenarios. The selection rules may improve the video coding and may also ensure that mismatch between video blocks at an encoder and a decoder is not introduced by the deblock filtering.

摘要： Error concealment is used to hide the effects of errors detected within digital video information. A complex error concealment mode decision is disclosed to determine whether spatial error concealment (SEC) or temporal error concealment (TEC) should be used. The error concealment mode decision system uses different methods depending on whether the damaged frame is an intra-frame or an inter-frame. If the video frame is an intra-frame then a similarity metric is used to determine if the intra-frame represents a scene-change or not. If the video frame is an intra-frame, a complex multi-termed equation is used to determine whether SEC or TEC should be used. A novel spatial error concealment technique is disclosed for use when the error concealment mode decision determines that spatial error concealment should be used for reconstruction. The novel spatial error concealment technique divides a corrupt macroblock into four different regions, a corner region, a row adjacent to the corner region, a column adjacent to the corner region, and a remainder main region. Those regions are then reconstructed in that order and information from earlier reconstructed regions may be used in later reconstructed regions. Finally, a macroblock refreshment technique is disclosed for preventing error propagation from harming non-corrupt inter-blocks. Specifically, an inter-macroblock may be 'refreshed' using spatial error concealment if there has been significant error caused damage that may cause the inter-block to propagate the errors.
摘要翻译：错误隐藏用于隐藏数字视频信息中检测到的错误的影响。公开了复杂的错误隐藏模式决定以确定是否应该使用空间错误隐藏（SEC）或时间错误隐藏（TEC）。错误隐藏模式决定系统根据损坏的帧是帧内帧还是帧间帧使用不同的方法。如果视频帧是帧内帧，则使用相似性度量来确定帧内帧是否表示场景变化。如果视频帧是帧内帧，则使用复杂的多项式来确定是否应使用SEC或TEC。公开了一种新颖的空间错误隐藏技术，用于当错误隐藏模式决定确定空间错误隐藏应该用于重建时。新颖的空间错误隐藏技术将损坏的宏块划分为四个不同的区域，即拐角区域，与拐角区域相邻的行，与拐角区域相邻的列以及剩余主区域。那些区域然后按该顺序重建，并且来自较早重建区域的信息可以用于稍后重建区域中。最后，公开了一种宏块更新技术，用于防止错误传播损害非损坏的块间。具体而言，如果存在可能导致块间传播错误的显着错误导致的损害，则可以使用空间错误隐藏来“刷新”宏块间宏块。

摘要： The disclosure describes FGS video coding techniques that use cycle-aligned fragments (CAFs). The techniques may perform cycle-based coding of FGS video data block coefficients and syntax elements, and encapsulate cycles in fragments for transmission. The fragments may be cycle-aligned such that a start of a payload of each of the fragments substantially coincides with a start of one of the cycles. In this manner, cycles can be readily accessed via individual fragments. Some cycles may be controlled with a vector mode to scan to a predefined position within a block before moving to another block. In this manner, the number of cycles can be reduced, reducing the number of fragments and associated overhead. The CAFs may be entropy coded independently of one another so that each fragment may be readily accessed and decoded without waiting for decoding of other fragments. Independent entropy coding may permit parallel decoding and simultaneous processing of fragments.
摘要翻译：本公开描述了使用循环对准片段（CAF）的FGS视频编码技术。这些技术可以执行FGS视频数据块系数和语法元素的基于循环的编码，并且将循环封装成用于传输的片段。片段可以是循环对齐的，使得每个片段的有效载荷的开始基本上与循环中的一个的开始重合。以这种方式，可以容易地通过各个片段访问周期。可以通过向量模式来控制一些周期，以便在移动到另一个块之前扫描到块内的预定位置。以这种方式，可以减少周期数，减少片段的数量和相关的开销。 CAF可以彼此独立地进行熵编码，使得每个片段可以容易地被访问和解码，而不等待其他片段的解码。独立熵编码可以允许并行解码和片段的同时处理。

摘要： An adaptive Intra-refresh (IR) technique for digital video encoding adjusts IR rate based on video content, or a combination of video content and channel condition. The IR rate may be applied at the frame level or macroblock (MB) level. At the frame level, the IR rate specifies the percentage of MBs to be Intra-coded within the frame. At the MB level, the IR rate defines a statistical probability that a particular MB is to be Intra-coded. The IR rate is adjusted in proportion to a combined metric that weighs estimated channel loss probability, frame-to-frame variation, and texture information. The IR rate can be determined using a close-form solution that requires relatively low implementation complexity. For example, such a close-form does not require iteration or an exhaustive search. In addition, the IR rate can be determined from parameters that are available before motion estimation and compensation are performed.
摘要翻译：用于数字视频编码的自适应内部刷新（IR）技术基于视频内容或视频内容和频道条件的组合来调整IR速率。可以在帧级或宏块（MB）级应用IR速率。在帧级别，IR速率指定帧内帧内编码的百分比。在MB级别，IR率定义了特定MB被内部编码的统计概率。 IR速率与重量估计的信道丢失概率，帧到帧变化和纹理信息的组合度量成比例地调整。 IR速率可以使用需要较低实现复杂度的紧密形式的解决方案来确定。例如，这种关闭形式不需要迭代或穷尽搜索。另外，可以在执行运动估计和补偿之前可用的参数来确定IR速率。

摘要： Techniques for estimating distortion due to quantization of data are described. A histogram with multiple bins may be obtained for a set of coefficients to be quantized. Distortion due to quantization of the set of coefficients may be estimated based on the histogram and average distortions for the histogram bins. The number of coefficients in each bin may be multiplied with an average distortion for the bin to obtain a per-bin distortion. The per-bin distortions for all of the bins may be accumulated and scaled with a correction factor to obtain the estimated distortion. The techniques may be used to estimate distortions for a set of coding elements. Distortion and rate may be estimated for each coding element for each of multiple quantization steps. A set of quantization steps may be selected for the set of coding elements based on the estimated distortions and the estimated rates for the set of coding elements for different quantization steps.

摘要： A monoscopic low-power mobile device is capable of creating real-time stereo images and videos from a single captured view. The device uses statistics from an autofocusing process to create a block depth map of a single capture view. Artifacts in the block depth map are reduced and an image depth map is created. Stereo three-dimensional (3D) left and right views are created from the image depth map using a Z-buffer based 3D surface recover process and a disparity map which is a function of the geometry of binocular vision.
