De-Blocking Filtering Control |
摘要 |
A block-specific filter decision value is calculated for a pixel block (10) in a video frame. If the block-specific filter decision value is below a block-specific threshold, each row or column (12) in the block (10) is individually processed in order to select between a strong and a weak de-blocking filter. A respective line-specific filter decision value is thereby calculated for each row or column (12) in the block (10) and compared to a line-specific threshold. If the line-specific filter decision value calculated for a row or column (12) is below the line-specific threshold a strong de-blocking filter is selected for the row or column (12), otherwise a weak de-blocking filter is instead selected to combat any blocking artifacts.
