Loop filtering across constrained intra block boundaries in video coding

摘要

This disclosure describes techniques for coding video data. In particular, this disclosure describes techniques for loop filtering for video coding. The techniques of this disclosure may apply to loop filtering and/or partial loop filtering across block boundaries in scalable video coding processes. Loop filtering may include, for example, one or more of adaptive loop filtering (ALF), sample adaptive offset (SAO) filtering, and deblocking filtering.

1. A method of video coding, the method comprising:
coding a block of video data according to a scalable video coding process using one of inter layer prediction or constrained intra-prediction to produce a reconstructed block of the video data; and applying a Sample Adaptive Offset (SAO) filter to pixels of the reconstructed block but limiting the application of the SAO filter by skipping, in response to a determination that a neighboring block of video data that neighbors the reconstructed block is not intra-coded, application of the SAO filter to boundary pixels of the reconstructed block.
