摘要： A filter unit of a video encoder or video decoder can determine a first metric for a group of pixels within a block of pixels based on a comparison of a subset of the pixels in the block to other pixels in the block; determine a filter based on the first metric; and generate a filtered image by applying the filter to the group of pixels. The subset of pixels can be selected to not include pixels on the boundary of the block of pixels.

摘要： Filtering is applied at an encoder, and filter information describing a set of filters is encoded in the bitstream to enable a decoder to identify the filtering that was applied at the encoder. The decoder receives encoded video data that includes the filter information, decodes the video data, and applies filtering based on the filtering information. The decoder applies the same filtering that was applied at the encoder. To potentially reduce the number of bits needed to reconstruct the set of filters and other filter information as well as to potentially improve decoder performance, filter description syntax describing the set of filters can be included in the bitstream. The filter description syntax may identify a number of filters in a set of filters, a maximum number of filters in a set of filters, and/or identify a shape of filters in a set of filters.

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.

摘要： The techniques of this disclosure apply to loop filtering across slice or tile boundaries in a video coding process. In one example, a method for performing loop filtering in a video coding process includes determining that pixels corresponding to filter coefficients of a filter mask for a loop filter are across a slice or tile boundary, removing filter coefficients corresponding to the pixels across the slice or tile boundary from the filter mask, renormalizing the filter mask without the removed filter coefficients, performing loop filtering using the renormalized filter mask.

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： 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： 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： During a prediction stage of video coding, a video coder may use relatively longer interpolation filters to generate predictive sub-pixel values using values of reference integer pixels of a reference block of video data positioned in parallel relative to a scanning order associated with the block and may use relatively shorter interpolation filters to generate predictive sub-pixel values using values of reference integer pixels of the block positioned perpendicular relative to the scanning order, wherein a longer interpolation filter generally refers to a filter with relatively more filter coefficients, or “taps,” and a shorter filter generally refers to a filter with relatively fewer taps.
