the following project.
Scalable video coding (SVC) is an ongoing video coding standard that is an
extension of H.264/advanced video coding. The goal of SVC is to provide
scalability at the bitstream level with good compression efficiency by
allowing combinations of scalable layers, including the spatial layer,
temporal layer, and signal-to-noise ratio layer. This enables a simple and
flexible solution for transmission over heterogeneous networks. Coding
efficiency in SVC has significantly improved; however, an extremely high
computational complexity is still required in determining the optimal
coding mode for each macro-block. Coding modes are selected by using
variable block-size motion estimation. Therefore, it is desirable to
develop optimization algorithms to reduce the computational complexity of
SVC without compromising the coding efficiency. In this project, three
research directions are proposed to reduce the computational complexity of
SVC while keeping the coding efficiency unchanged:
* explore the mode-distribution correlation in SVC to build mode
prediction models for shrinking the mode selection range;
* present advanced techniques to develop fast-mode decision and motion
estimation algorithms to reduce the computational complexity of SVC; and
* consider the optimizing of the discrete cosine transform and
quantization functions to further reduce the SVC computations.
