摘要： For a first series of video blocks, an encoder determines two filters, a first decoding filter that is to be transmitted to a decoder and a first interim filter that is not to be transmitted to the decoder. The first interim filter is used to determine which coded units of a second series of video blocks are to be filtered. After a decision is made as to which coded units of the second series of video blocks are to be filtered, the encoder determines a second decoding filter for the second series of video blocks and transmits the second decoding filter to the decoder. In addition to determining the second decoding filter, the encoder also determines a second interim filter, which the encoder uses to determine which coded units of a third series of video blocks are to be filtered. This process may repeat for many series of video blocks.

摘要： Filtering is applied at a video encoder, and filter information is encoded in the bitstream to enable a video decoder to identify the filtering that was applied at the video encoder. The video decoder receives encoded video data that includes the filter information, decodes the video data, and applies filtering based on the filtering information. In this way, the decoder applies the same filtering that was applied at the encoder. Video can be encoded utilizing multiple filters with Laplacian filter indexing for multiple inputs for coded units partitioned using a quadtree partitioning scheme.

摘要： An interim filter determined for a previous series of video blocks can be applied to a current series of video blocks to determine an interim filter map for the current series of video blocks. Based on the interim filter map, a decoding filter can be determined. By applying the decoding filter to the current series of video blocks, a decoding filtering map can be determined. Based on CUs identified as having filtering off by the decoding filtering map, an interim filter for the current series of video blocks can be determined. The decoding filter and decoding filtering map can be transmitted to a decoder, while the interim filter and interim filter map may not be transmitted to a decoder. The interim filter for the current series of video blocks can be used to generate an interim filter map for a next series of video blocks.

摘要： This disclosure describes techniques for performing sample adaptive offset signaling and coding in a video coding process. Techniques of the disclosure include both a merge-based and prediction-based signaling process for sample adaptive offset information (i.e., offset values and offset type). The techniques includes determining offset information for a current partition, comparing the offset information of the current partition with offset information of one or more neighbor partitions, coding a merge instruction in the case that the offset information of one of the one or more neighbor partitions is the same as the offset information of the current partition, and coding one of a plurality of prediction instructions in the case that the offset information of the one or more neighbor partitions is not the same as the offset information of the current partition.

摘要： A filter unit determines a mapping of range combinations to filters. Each range combination includes a range for a first metric and a range for a second metric. The filter unit determines a unique range combination identification (ID) for each range combination, with each unique range combination ID corresponding to a sequential value. The filter unit assigns a unique group ID to each group of range combinations. A group of range combinations includes range combinations mapped to the same filter, and the unique group IDs correspond to a set of sequential values. The filter unit signals or reconstructs coefficients for the filters in an order based on the sequential values of the group IDs.

摘要： Techniques for coding both edge and band offset values are described. Offset values may be predicted such that one offset value in a group of offset values is predicted from another offset value in the group. In addition, offset values of a partition may be predicted from offset values of a neighboring partition. Offset values may also be right shifted to be at a lower precision before signaling in the encoded video bitstream. A video decoding device may apply the techniques to filter a current partition based on offset values associated with a neighboring partition.

摘要： In general, techniques are described for applying partition-based filters when coding video data. A device comprising at least one processor may be configured to implement the techniques. The processor selects a filter to apply near a boundary of a first portion of the video data and determines at least one of the plurality of filter coefficients of the selected filter for which the video data will not be available to be filtered. Based on the determination, the processor determines a partial filter that does not include the at least one of the plurality of filter coefficients for which the video data will not be available to be filtered. The processor renormalizes the plurality of filter coefficients included within the partial filter and applies the renormalized partial filter near the boundary of the first portion of the video data to generate a filtered first portion of the video data.

摘要： An encoder can generate a series of codewords to signal to a decoder a mapping of range combinations for two or more metrics. The encoder can generate a first codeword to indicate a current combination being decoded maps to the same filter as the most recently decoded combination that shares the same range for the first metric. The encoder can generate a second codeword to indicate that the current combination maps to the same filter as the most recently decoded combination that shares the same range for the second metric. If the current combination does not map to the same filter as either of these most recently decoded combinations, then the encoder can generate a third codeword that indicates the filter that maps to the current combination.
