METHODS AND APPARATUS FOR ARTIFACT REMOVAL FOR BIT DEPTH SCALABILITY |
摘要 |
Apparatus and methods are described for encoding and decoding an enhancement layer. A deblocking filter is applied at the enhancement layer for bit depth scalability. The deblocking filter is adjusted to remove coding artifacts caused by local inverse tone mapping for intra-layer texture prediction for the bit depth scalability. The boundary strength of the deblocking filter is adjusted based on a threshold that, in turn, is based on a difference of inverse tone mapping parameters for a block and an adjacent block. |
