Abstract
Description
本出願は、その開示全体が参照により本明細書に組み込まれている、2015年6月8日に出願された米国特許仮出願第62/172,645号明細書、2015年10月14日に出願された米国特許仮出願第62/241,708号明細書、および2016年2月19日に出願された米国特許仮出願第62/297,736号明細書の利益を主張するものである。
WP(x,y)=w・P(x,y)+o (13)
P(x,y)およびWP(x,y)はそれぞれ重み付き予測の前および後の位置(x,y)における予測された画素値とすることができ、wおよびoは重み付き予測において用いられる重みおよびオフセットとすることができる。双方向予測使用のケースにおいて重み付き予測は、式14によって示される2つの時間的予測信号の線形結合から行われることができる。
WP(x,y)=(w0−P0(x,y)+W1P1(x,y)+O0+O1)/2 (14)
P0(x,y)およびP1(x,y)は重み付き予測の前の第1および第2の予測ブロックとすることができ、WP(x,y)は重み付き予測の後の双方向予測信号とすることができ、w0およびw1は各予測ブロックに対する重みとすることができ、およびO0およびO1は各予測ブロックに対するオフセットとすることができる。
