12-1 DCTを利用した複数の直交変換によるインター符号化(第12部門[テーマ講演]HVEC符号化)

抄録

This paper describes the transform coding with orthogonal transforms which is derived from DCT. These transforms are switched due to the relative positions between a prediction unit and a transform unit. The performance is evaluated with HEVC Test Model (HM) ver. 6.0. The results showed 1.3 % bit saving on average than the original coding scheme.
