Optimal bounds on texture coe cients
نویسنده
چکیده
Let w be the orientation distribution function of a polycrystalline aggregate of crystallites with symmetry G cr and with group of texture symmetry G tex. In this paper we obtain a \recipe" on how to derive optimal bounds on the texture coeecients W lmn associated with w. In particular, we nd explicit bounds in the case in which G tex is a group with orthorhombic symmetry and G cr is either a group with cubic symmetry or a group with hexagonal symmetry.

Incorporating Information on Neighboring Coe cients into Wavelet Estimation
In standard wavelet methods, the empirical wavelet coe cients are thresholded term by term, on the basis of their individual magnitudes. Information on other coe cients has no in uence on the treatment of particular coe cients. We propose and investigate a wavelet shrinkage method that incorporates information on neighboring coe cients into the decision making. The coe cients are considered in ...

Vlad BALLY (Université Marne-la-Vallée, France) Density estimates for local-stochastic volatility models Abstract : We consider a stochastic volatility model of Heston type but we allow the coe cients to depend on the state (the volatility and the stock price). This is a generalization of the classical Heston model which seems to be of increasing interest in the nancial industry nowadays. Our a...
متن کاملProgressive wavelet image coding based on a conditional probability model
We present a wavelet image coder based on an explicit model of the conditional statistical relationships between coe cients in di erent subbands. In particular, we construct a parameterized model for the conditional probability of a coe cient given coe cients at a coarser scale. Subband coe cients are encoded one bitplane at a time using a non-adaptive arithmetic encoder. The overall ordering o...
متن کاملRestricted-Recourse Bounds for Stochastic Linear Programming
We consider the problem of bounding the expected value of a linear program (LP) containing random coe&cients, with applications to solving two-stage stochastic programs. An upper bound for minimizations is derived from a restriction of an equivalent, penalty-based formulation of the primal stochastic LP, and a lower bound is obtained from a restriction of a reformulation of the dual. Our “restr...
متن کاملSignificance-linked connected component analysis for high performance low bit rate wavelet coding
Recent success in wavelet image coding is mainly attributed to the recognition of importance of data organization and representation. There have been several very competitive wavelet coders developed, namely, embedded zerotree wavelets (EZW), morphological representation of wavelet data (MRWD), and set partitioning in hierarchical trees (SPIHT). In this paper, we develop a novel wavelet image c...
