摘要： Various implementations provide filtering for pictures. Several such implementations attempt to reduce artifacts caused by over-filtering in a decoding loop. Certain of these implementations provide multiple loop filters, and select a loop filter based on the result of a deblocking 5 filter. One particular implementation applies a first filter to a picture to produce a filtered picture. A second filter is selected based on a difference between a value of a particular pixel in the filtered picture and a value of a corresponding pixel in the picture. The second filter is applied to the particular pixel in the filtered picture. In another implementation, a signal or signal structure includes 10 an indication of the second filter, an encoding of at least a portion of a picture, and an encoding of at least a portion of a subsequent picture that has been encoded based on the output of the second filter above.
