Weight-based R-λ rate control for perceptual HEVC coding on conversational videos
作者：
Highlights：
• Our work is based on the latest R-λ rate control scheme.
• Besides face regions, the regions inside the faces are treated with unequal importance.
• We conduct eye tracking experiments to learn the importance weights of different regions from training videos.
• The bits are perceptually allocated according to the term of bit per weight (bpw).
• We introduce the objective and subjective quality assessments together to make experimental results more reasonable.
