Spatial Normalization using Basis Functions
This chapter describes the steps involved in registering images of different subjects into roughly the same co-ordinate system, where the co-ordinate system is defined by a template image (or series of images). The method only uses up to a few hundred parameters, so can only model global brain shape. It works by estimating the optimum coefficients for a set of bases, by minimizing the sum of sq...
متن کاملNormalization of monomial ideals and Hilbert functions
We study the normalization of a monomial ideal and show how to compute its Hilbert function if the ideal is zero dimensional. A positive lower bound for the second coefficient of the Hilbert polynomial is shown. 1 Normalization of monomial ideals In the sequel we use [3, 11] as references for standard terminology and notation on commutative algebra and polyhedral cones. We denote the set of non...
متن کاملNormalization integrals of orthogonal Heun functions
A formula for evaluating the quadratic normalization integrals of orthogonal Heun functions over the real interval 0 ≤ x ≤ 1 is derived using a simple limiting procedure based upon the associated differential equation. The resulting expression gives the value of the normalization integral explicitly in terms of the local power-series solutions about x = 0 and x = 1 and their derivatives. This p...
متن کاملA frequency warping approach to speaker normalization
In an effort to reduce the degradation in speech recognition performance caused by variations in vocal tract shape among speakers, this thesis studies a set of lowcomplexity, maximum likelihood based speaker normalization procedures. By approximately modeling the vocal tract as a simple acoustic tube, these procedures compensate for the effects of the variations in vocal tract length by linearl...
متن کاملSpeaker normalization based on frequency warping
In speech recognition, speaker-dependence of a speech recognition system comes from speaker-dependence of the speech feature, and the variation of vocal tract shape is the major source of inter-speaker variations of the speech feature, though there are some other sources which also contribute. In this paper, we address the approaches of speaker normalization which aim at normalizing speaker's v...
