Query: Auto-Weighted Layer Representation Based View Synthesis Distortion
  Estimation for 3-D Video Coding   Recently, various view synthesis distortion estimation models have been
studied to better serve for 3-D video coding. However, they can hardly model
the relationship quantitatively among different levels of depth changes,
texture degeneration, and the view synthesis distortion (VSD), which is crucial
for rate-distortion optimization and rate allocation. In this paper, an
auto-weighted layer representation based view synthesis distortion estimation
model is developed. Firstly, the sub-VSD (S-VSD) is defined according to the
level of depth changes and their associated texture degeneration. After that, a
set of theoretical derivations demonstrate that the VSD can be approximately
decomposed into the S-VSDs multiplied by their associated weights. To obtain
the S-VSDs, a layer-based representation of S-VSD is developed, where all the
pixels with the same level of depth changes are represented with a layer to
enable efficient S-VSD calculation at the layer level. Meanwhile, a nonlinear
mapping function is learnt to accurately represent the relationship between the
VSD and S-VSDs, automatically providing weights for S-VSDs during the VSD
estimation. To learn such function, a dataset of VSD and its associated S-VSDs
are built. Experimental results show that the VSD can be accurately estimated
with the weights learnt by the nonlinear mapping function once its associated
S-VSDs are available. The proposed method outperforms the relevant
state-of-the-art methods in both accuracy and efficiency. The dataset and
source code of the proposed method will be available at
