    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 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： 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： 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.
