An efficient rate–distortion optimization method for dependent view in MV-HEVC based on inter-view dependency

作者：

Highlights：

• First of all, by investigating the sources of the distortion in the DV, a new distortion model for the DV is established.

• In addition, based on the proposed distortion model, an efficient Lagrangian multiplier decision for B frame is proposed by considering the inter-view dependency.

• Finally, the optimized Lagrangian multiplier for P frame is designed using the scaling factor which is deduced to have a linear relationship with the disparity between I frame and P frame.
