Restricted Intra Deblocking Filtering For Video Coding

摘要

A filtering control involves checking a block size of an intra-predicted block (4, 5, 7) of pixels of a picture (2) in a video sequence (1). The block size is compared to a specified threshold. It is then determined, based on the comparison of the block size to the specified threshold, whether to apply filtering to top-most and/or left-most pixels in the intra-predicted block (4, 5, 7) of pixels. The embodiments thereby improve the subjective quality of intra-prediction, while still keeping the objective gains brought by filtering.

1. A filtering control method comprising:
checking (S1, S1′) a block size of an intra-predicted block (4, 5, 7) of pixels of a picture (2) in a video sequence (1); comparing (S2, S2′) said block size to a specified threshold; and determining (S3, S3′) whether to apply filtering of top-most and/or left-most pixels in said intra-predicted block of pixels based on said comparison of said block size to said specified threshold.
