Temporal dependent rate-distortion optimization based on distortion backward propagation

Temporal dependent rate-distortion optimization based on distortion backward propagation

Show other versions (1)

Rate-distortion optimization (RDO) is a crucial technique in block based hybrid video encoders.However, the widely used independent RDO is far from obtaining optimal coding performance.To improve the rate-distortion (R-D) performance of high efficiency video coding (HEVC), a temporal dependent RDO a...
