摘要： A motion-compensated video encoding scheme employs progressive fine-granularity layered coding to encode macroblocks of video data into frames having multiple layers, including a base layer of comparatively low quality video and multiple enhancement layers of increasingly higher quality video. Some of the enhancement layers in a current frame are predicted from different quality layers in reference frames. The video encoding scheme estimates drifting errors during the encoding and chooses a coding mode for each macroblock in the enhancement layer to maximize high coding efficiency while minimizing drifting errors.

摘要： A scalable layered video coding scheme that encodes video data frames into multiple layers, including a base layer of comparatively low quality video and multiple enhancement layers of increasingly higher quality video, adds error resilience to the enhancement layer. Unique resynchronization marks are inserted into the enhancement layer bitstream in headers associated with each video packet, headers associated with each bit plane, and headers associated with each video-of-plane (VOP) segment. Following transmission of the enhancement layer bitstream, the decoder tries to detect errors in the packets. Upon detection, the decoder seeks forward in the bitstream for the next known resynchronization mark. Once this mark is found, the decoder is able to begin decoding the next video packet. With the addition of many resynchronization marks within each frame, the decoder can recover very quickly and with minimal data loss in the event of a packet loss or channel error in the received enhancement layer bitstream. The video coding scheme also facilitates redundant encoding of header information from the higher-level VOP header down into lower level bit plane headers and video packet headers. Header extension codes are added to the bit plane and video packet headers to identify whether the redundant data is included.

摘要翻译：将视频数据帧编码成多层的可分级的分层视频编码方案，包括具有越来越高质量视频的较低质量视频和多个增强层的基本层，向增强层增加了错误恢复能力。将独特的再同步标记插入到与每个视频分组相关联的报头中的增强层比特流中，与每个位平面相关联的报头以及与每个视频平面（VOP）段相关联的报头。在传输增强层比特流之后，解码器尝试检测分组中的错误。在检测到时，解码器在比特流中向前寻找下一个已知的再同步标记。一旦找到该标记，解码器就可以开始对下一个视频数据包进行解码。通过在每个帧内添加许多重新同步标记，解码器可以在接收到的增强层比特流中的分组丢失或信道错误的情况下非常快速地恢复并且具有最小的数据丢失。视频编码方案还有助于将标题信息从较高级别的VOP头部冗余编码到较低级位平面头部和视频分组头部。标题扩展码被添加到位平面和视频分组报头，以标识是否包括冗余数据。

摘要： Innovations in encoder-side decisions for coding of screen content video or other video can speed up encoding in various ways. For example, some of the innovations relate to ways to speed up motion estimation by identifying appropriate starting points for the motion estimation in different reference pictures. Many of the encoder-side decisions speed up encoding by terminating encoding for a block or skipping the evaluation of certain modes or options when a condition is satisfied. For example, some of the innovations relate to ways to speed up encoding when hash-based block matching is used. Still other innovations relate to ways to identify when certain intra-picture prediction modes should or should not be evaluated during encoding. Other innovations relate to other aspects of encoding.

摘要： A dislocation-free high quality template with relaxed lattice constant, fabricated by spatially restricting misfit dislocation(s) around heterointerfaces. This can be used as a template layer for high In composition devices. Specifically, the present invention prepares high quality InGaN templates (In composition is around 5-10%), and can grow much higher In-composition InGaN quantum wells (QWs) (or multi quantum wells (MQWs)) on these templates than would otherwise be possible.

摘要： An adaptive depth sensing system (ADSS) illuminates a scene with a pattern that is constructed based on an analysis of at least one prior-generated depth map. In one implementation, the pattern is a composite pattern that includes two or more component patterns associated with different depth regions in the depth map. The composite pattern may also include different illumination intensities associated with the different depth regions. By using this composite pattern, the ADSS can illuminate different objects in a scene with different component patterns and different illumination intensities, where those objects are located at different depths in the scene. This process, in turn, can reduce the occurrence of defocus blur, underexposure, and overexposure in the image information.

摘要： Disclosed herein are exemplary embodiments of methods, apparatus, and systems for performing content-adaptive deblocking to improve the visual quality of video images compressed using block-based motion-predictive video coding. For instance, in certain embodiments of the disclosed technology, edge information is obtained using global orientation energy edge detection (“OEED”) techniques on an initially deblocked image. OEED detection can provide a robust partition of local directional features (“LDFs”). For a local directional feature detected in the partition, a directional deblocking filter having an orientation corresponding to the orientation of the LDF can be used. The selected filter can have a filter orientation and activation thresholds that better preserve image details while reducing blocking artifacts. In certain embodiments, for a consecutive non-LDF region, extra smoothing can be imposed to suppress the visually severe blocking artifacts.
摘要翻译：这里公开了用于执行内容自适应解块以改善使用基于块的运动预测视频编码压缩的视频图像的视觉质量的方法，装置和系统的示例性实施例。例如，在所公开的技术的某些实施例中，边缘信息是使用最初去块图像上的全局取向能量边缘检测（“OEED”）技术获得的。 OEED检测可以提供局部方向特征（“LDFs”）的鲁棒分区。对于在分区中检测到的局部方向特征，可以使用具有与LDF的取向对应的取向的定向去块滤波器。所选择的过滤器可以具有过滤器方向和激活阈值，以更好地保留图像细节，同时减少块伪影。在某些实施例中，对于连续的非LDF区域，可以施加额外的平滑来抑制视觉上严重的块状伪影。
