Rate-Distortion Modeling and its Application to Quality Layer Assignment in SVC/H.264 Fine-Granular SNR Scalable Videos
Rate-Distortion Modeling Quality Layer Assignment SVC/H.264 Fine-Granular SNR Scalable Videos
2007/12/31
To support efficient quality extraction in H.264/AVCbased scalable video coding, it’s important to obtain the rate-distortion (R-D) or distortion-rate (D-R) function of
each FGS packet. In this paper...
A Simple Algorithm for Constant Quality Reconstruction of Scalable video Using a New Analytical R-D Model,
Constant Quality Scalable video Analytical R-D Model
2006/12/31
In this paper, we first introduce the analytical R-D model of scalable video in our recent work. The R-D model is induced by the R-D analysis of Generalized Gaussian Distribution (GGD). Then we propos...
