This book presents original results on the leading edge of computer science research. Each article has been carefully selected in an attempt to present substantial research results across a broad spectrum. Topics discussed include weighted fusion of shape descriptor for robust shape classification; metaheuristics for curve and surface reconstruction; stream-based parallel computing methodology and development environment for high performance many core accelerators; h-infinity recursive wiener fixed-interval smoother based on innovation approach in linear discrete-time stochastic systems; and virtual supercomputers as the basis of scientific computing.
