An efficient Lagrangian multiplier selection method based on temporal dependency for rate–distortion optimization in H.265/HEVC

作者:

Highlights:

• Temporal dependency is considered in the proposed method.

• Temporal relationship of distortion and bit-rate among layers were investigated.

• Average BD-rate reduction for the RA configuration is 4.59%.

• The proposed method in this paper is content adaptive for practical use.
