Representation of Head Related Transfer Functions with Principal Component Analysis
Head Related Transfer Functions (HRTFs) describe the changes in the sound wave as it propagates from a spatial sound source to the human eardrum. One possible representation of HRTF data is the use of Principal Component Analysis (PCA), which decomposes data to principal components and corresponding weights. We applied PCA to MIT Media Lab nonindividualized HRTF library. The linear amplitudes o...
متن کاملMultivariate polynomial interpolation: Aitken-Neville sets and generalized principal lattices
A suitably weakened definition of generalized principal lattices is shown to be equivalent to the recent definition of Aitken-Neville sets. The recent paper [CGS08] explores the relationship of Aitken-Neville sets, introduced in [SX], to generalized principal lattices, introduced in [CGS06]. Both are subsets X of F (with F equal to R or C) that are n-correct for some n in the sense that, with Π...
متن کاملHead-related transfer function interpolation in azimuth, elevation, and distance.
Although distance-dependent head-related transfer function (HRTF) databases provide interesting possibilities, e.g., for rendering virtual sounds in the near-field, there is a lack of algorithms and tools to make use of them. Here, a framework is proposed for interpolating HRTF measurements in 3-D (i.e., azimuth, elevation, and distance) using tetrahedral interpolation with barycentric weights....
متن کاملOn Multivariate Interpolation by Weights
The aim of this paper is to study a particular bivariate interpolation problem, named interpolation by weights. A minimal interpolation space is derived for these interpolation conditions. An integral formula for the remainder is given, as well as a superior bound for it. An expression for g(D)(Ln(f)) is obtained.
متن کاملOn multivariate polynomial interpolation
We provide a map Θ 7→ ΠΘ which associates each finite set Θ of points in C with a polynomial space ΠΘ from which interpolation to arbitrary data given at the points in Θ is possible and uniquely so. Among all polynomial spaces Q from which interpolation at Θ is uniquely possible, our ΠΘ is of smallest degree. It is also Dand scale-invariant. Our map is monotone, thus providing a Newton form for...
