Spatial Scalability in 3D Wavelet Coding With Spatial Domain MCTF Encoder

Overview This paper investigates the spatial scalability in 3D wavelet coding with spatial-domain MCTF encoder. The paper analyzed the factors which lead to the performance degradation in heuristic decoding scheme where inverse MCTF is carried out in spatial lowpass wavelet domain as if it were the original video at encoder. The inefficiency of interpolation and motion compensation in wavelet domain, the commutation of spatial DWT and MCTF are found to be two factors. Furthermore, the power spectrum leak across subbands caused by motion compensation is another serious reason.

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
