Abstract
Description
本出願は、その開示が、これによってその全体が本明細書に組み込まれている、2013年9月24日に出願された米国特許仮出願第61/881,801号の利益を主張するものである。
ただし、n_bitsは因子Nのためのビット数であり、m_bitsは因子Mのためのビット数であり、Round(x)は次の整数値への下向きのxの丸めを表し、abs(x)はxの絶対値を表し、min(x,y)およびmax(x,y)はそれぞれxおよびyの最小および最大値を表す。
EILR(x,y)= Clip(ILRfilt(x,y)) (23)
EILR(x,y)=Clip(ILR(x,y)+ILMCfilt(x,y)) (26)
ILRfilt(x,y)=Round{[abs(SumLP(x,y)×MLP)+(1≪(NLP−1))]≫NLP}×sign(SumLP(x,y)×MLP) (30)
EILR(x,y)=Clip(ILRfilt(x,y)+ILMCfilt(x,y)) (31)
RDEILR=DEILR+λ(num_bits_coeff+num_bits_factor) (33)
ただしDILRおよびDEILRは、それぞれもとのEL画像と比較したときの、ILRおよびEILR画像の歪みを表すことができる。歪みを導出するために、非限定的に二乗誤差和(SSE)、差分絶対値和(SAD)、および/または変換差分絶対値和(SATD)などの種々のメトリックが適用され得る。num_bits_coeffは、量子化されたフィルタ係数を符号化するオーバーヘッドとすることができ、num_bits_factoは、因子Mおよびその対応するシフトNを符号化するオーバーヘッドとすることができる。λはラグランジュの重み付け因子とすることができる。RDEILRがRDILRより小さい場合は、EILR画像は、EL符号化の性能に関してILR画像より、強化されたレイヤ間予測品質と増加されるオーバーヘッドとの間の、より良好なトレードオフを示し得る。ILR強化方法は、EL画像に対してイネーブルされ得る。そうでない場合(例えばRDEILRがRDILR以上である場合)は、ILR強化はEL画像に対してディスエーブルされ得る。ILR強化の使用は、高レベルシグナリング方法によってデコーダ側にシグナリングされ得る。
