2D-to-3D conversion is one of the key technologies in stereoscopic video. Its visual qualities depend on the qualities of depth image estimation and virtual viewpoint image rendering. Although there are many methods to get depth information, the depth information still has some errors because of calculation errors and noises, which influences the visual qualities of the generated virtual viewpoint...
Compressive sampling (CS) theory and distributed video coding (DVC) are two techniques suitable to scenarios where a video codec with simple encoder and complex decoder is desired. The combination of CS theory and DVC is a new research trend in this field and several integrated schemes have now appeared. However, in these existing integrated schemes, the dependencies between measurements of successive...
We investigate the problem of constructing optimal layered multicast for heterogeneous sink nodes using network coding. Taking the flexibility of layered coding into account, we discuss the optimization problem that determines the optimal layers' bit-rates for layered multicast, and express it into a mathematical formulation. Finding that this formulation is nonlinear and difficult to solve, we reduce...
