METHOD AND APPARATUS FOR IMPROVING THE PREDICTION OF A BLOCK OF THE ENHANCEMENT LAYER

摘要

A method (350) includes: applying (S360) inverse tone mapping operations to a block (b b ) of a first layer (l b ) and to a prediction block (∼b b ) of the block (b b ) of the first layer (l b ), respectively, computing (S365) a residual prediction error (re b) in a second layer (l e ), and computing (S370) a prediction (p e ) of a block of the second layer (l e ).
