摘要： When an MPM list is constructed based on the frequency of the modes, the first MPM often has a frequency that is greater or comparable to the frequencies of the remaining MPMs combined. Thus, we propose to flag the first mode in the MPM list to indicate whether the current mode is the first mode in the sorted MPM list, and if not, a second flag can be used to inform if the current mode belongs to the rest of the MPM list. For some video data, the second entry in the MPM list may still be more probable than the rest of the modes combined. In this case, the encoder or decoder may add another flag to signal the second MPM. The method of signaling the intra prediction mode may be switched on or off based on the type of blocks.

摘要： The present disclosure relates to methods, apparatus or systems for encoding and decoding sequence of images by applying a global rotation motion compensation to an input image. According to different embodiments, the input image is a reference image in a compression loop or the image to be encoded. The images to encode are omnidirectional images. As a result, applying a global rotation motion compensation to them corresponds to generate new images as if they have been captured according to a different front direction. When this new front direction is the one of a reference image, the compensation of apparent motion is facilitated.

摘要： Sample Adaptive Offset (SAO) can be used for artifact reduction in video coding. Designing the categories in SAO based on the video content may improve the SAO efficiency. In one embodiment, the EO categories are determined based on whether a difference of a sample and neighboring samples is greater than a threshold or not. Introducing a threshold based on the bit depth of the video content into EO categorization may counter the impact of random noise that frequently occurs in the video content with a high bit depth. In addition, the threshold may be adjusted based on the directional pattern of a block. In one embodiment, the threshold for "EO_45" or "EO_135" may be greater than the threshold for "EO_0" or "EO_90."
摘要翻译：采样自适应偏移量（SAO）可用于视频编码中的伪像减少。基于视频内容设计SAO中的类别可以提高SAO效率。在一个实施例中，基于样本和相邻样本的差异是否大于阈值来确定EO类别。将基于视频内容的位深度的阈值引入到EO分类中可以抵消频繁出现在高位深度的视频内容中的随机噪声的影响。另外，可以基于块的方向图来调整阈值。在一个实施例中，“EO_45”或“EO_135”的阈值可以大于“EO_0”或“EO_90”的阈值。

摘要： Images to be used as reference images in an adaptive resolution coder or decoder undergo resizing to match the resolution of an image being processed. The resizing process is carried out using extended resolution bit lengths to more accurately represent the processed image. The internal bit depth is retained through the resizing process, and kept as a reference image is stored. When a reference image is used in motion compensation processing, the resized reference matches the resolution of a current image being processed and has an expanded bit depth precision to achieve better fidelity.
