摘要： This application discloses encoding and decoding methods and apparatuses, and relates to the field of artificial intelligence technologies, to improve rate distortion performance of data encoding and decoding methods. The method includes: first obtaining to-be-encoded data, and then inputting the to-be-encoded data into a first encoding network to obtain a target parameter; then constructing a second encoding network based on the target parameter; next inputting the to-be-encoded data into the second encoding network to obtain a first feature; and finally encoding the first feature to obtain an encoded bitstream.

摘要： Methods, apparatus, systems and articles of manufacture to perform block-based static region detection for video processing are disclosed. Disclosed example video processing methods include segmenting pixels in a first frame of a video sequence into a first plurality of pixel blocks. Such example methods can also include processing the first plurality of pixel blocks and a second plurality of pixel blocks corresponding to a prior second frame of the video sequence to create, based on a first criterion, a map identifying one or more static pixel blocks in the first plurality of pixel blocks. Such example methods can further include identifying, based on the map, a static region in the first frame of the video sequence.

摘要： In general, this disclosure describes techniques for coding video blocks using a color-space conversion process. A video coder, such as a video encoder or a video decoder, may determine whether to use color-space conversion for encoding the video data. In response to determining to use color-space conversion, the video coder may quantize data of a first color component of the video data using a first offset of a first quantization parameter (QP) and quantize data of a second color component of the video data using a second offset of a second QP, wherein the second color component is different than the first color component, and the second QP is different than the first QP. The video coder may further inverse quantize data of the first color component using the first offset and inverse quantize data of the second color component using the second offset.

摘要： A method of encoding or decoding coding units of a video content in a palette coding mode using an adaptive palette predictor is provided. The method includes adaptively determining a maximum size of the adaptive palette predictor based on at least one of a complexity of the video content and coding quality of the video content; and encoding or decoding the coding units of the video content in the palette coding mode using the adaptive palette predictor while limiting the adaptive palette predictor that is derived from all palette(s) of previously encoded or decoded coding unit(s) of the video content within the maximum size determined in the adaptively determining step. An apparatus of encoding or decoding coding units of a video content in a palette coding mode using an adaptive palette predictor is also provided.

摘要： A method for adaptive MV precision is disclosed. According to one embodiment, whether to use or not to use the adaptive MV precision for a current block is determined according to a prediction mode/partition type of the current block. If the adaptive MV precision is used, a current MV precision is determined for a current MV of the current block, and the current MV is encoded or decoded at the current MV precision. If the adaptive MV precision is not used, the current MV is encoded or decoded at a finer MV precision. In another embodiment, a value of a current adaptive MV precision flag is selected for a current block to indicate whether to use or not to use the adaptive MV precision for a current block according to a prediction mode/partition type of the current block.

摘要： Techniques are described for a video coder (e.g., video encoder or video decoder) that is configured to select a context pattern from a plurality of context patterns that are the same for a plurality of scan types. Techniques are also described for a video coder that is configured to select a context pattern that is stored as a one-dimensional context pattern and identifies contexts for two or more scan types.

摘要： A method, apparatus, article of manufacture, and a memory structure for signaling the storage of motion information describing the depicted motion associated with digital pictures. In one embodiment, the method comprises signaling the replacement of a motion vector stored in connection with a previously coded picture with the motion vector of the currently coded frame. Another signal may be used to indicate motion vector replacement for all pictures in a sequence.
