Wavelet transform coefficient encoders are broadly categorized as depending on correlations: across sub-bands through a zerotree, or within sub-bands through a block quad-tree. Th...
In this paper we present a set of formulations that describe some properties of the configurations that can represent the n-Dimensional Orthogonal PseudoPolytopes. Moreover, we de...
We address the problem of rough applicability of rules within the framework of approximation spaces. The graded applicability of a rule for an object of an approximation space, int...
Credit risk analysis for portfolios containing CDO tranches is a challenging task for risk managers. We propose here a basis function approach for CDO tranche valuation and portfo...
A hybrid video coding scheme which combines fractal coding with neighbourhood vector quantisation is reported. While fractal coding exploits the redundancy present in different sc...
