Influence of the Discretization Scheme on the Parallel Efficiency of a Code for the Modelling of a Ucomparison of the parallel efficiency of the code using the hybrid central differences/upwind and the MUSCL schemes for the discretization of the convective terms of the governing equations. The results were obtained using a Cray T3D and a number of processors in the range 1 – 128. It is shown that

Zhaojun Bai,Gene H. Golubin. We propose an alternative approach, where an accurate estimation in the pixel domain is followed by a novel method of transforming the pixel-domain estimation into the transform domain. The experimental results show that our model leads to average bit-rate gain of 3.5–8%.

Experiments show that the proposed method can yield more desirable compressed visual content than the other sampling based coding methods (and also in comparison with coding methods without down sampling) and automate the switching of the sampling modes for variable bit rate application.
