Abstract
Apparatus and methods are described for encoding and decoding image data for image blocks which form a picture by having a deblocking filter remove coding artifacts caused by local inverse tone mapping for intra-layer texture prediction for bit depth-scalability. 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 is based on a difference of inverse tone mapping parameters for the block and at least one adjacent block with respect to the block.
