JEFFREYKIRWANWITTEN LOCALIZATION FORMULA FOR REDUCTIONS AT REGULAR COADJOINT ORBITS
"... For MarsdenWeinstein reduction at the point 0 in g∗, the wellknown JeffreyKirwanWitten localization formula was proven and then by M. Vergne modified. We prove in this paper the same kind formula for the reduction at regular coadjoint orbits by using the universal orbital formula of characters ..."

Coil sensitivity encoding for fast MRI. In:
 Proceedings of the ISMRM 6th Annual Meeting,
, 1998
"... New theoretical and practical concepts are presented for considerably enhancing the performance of magnetic resonance imaging (MRI) by means of arrays of multiple receiver coils. Sensitivity encoding (SENSE) is based on the fact that receiver sensitivity generally has an encoding effect complementa ..."

to noise a SENSE reconstructed image may be impaired by errors of systematic nature. Errors in sample values may be due, e.g., to tissue motion, main field inhomogeneity, eddy currents, or gradient nonlinearity. The related artifacts are well known in standard imaging. A potential problem specific
On RiemannRoch formulas for multiplicities
 J. Amer. Math. Soc
"... A Theorem due to Guillemin and Sternberg [17] about geometric quantization of Hamiltonian actions of compact Lie groups G on compact Kähler manifolds says that the dimension of the Ginvariant subspace is equal to the RiemannRoch number of the symplectically reduced space. Combined with the shiftin ..."

where the reduced space may have orbifold singularities. Our proof uses localization techniques from equivariant cohomology, and relies in particular on recent work of JeffreyKirwan [20] and Guillemin [14]. Since there are no complex geometry arguments involved, the result also extends to non Kählerian
A ClosedForm Solution to Natural Image Matting
 IEEE TRANS. PAMI
, 2008
"... Interactive digital matting, the process of extracting a foreground object from an image based on limited user input, is an important task in image and video editing. From a computer vision perspective, this task is extremely challenging because it is massively illposed—at each pixel we must estim ..."

estimate the foreground and the background colors, as well as the foreground opacity (“alpha matte”) from a single color measurement. Current approaches either restrict the estimation to a small part of the image, estimating foreground and background colors based on nearby pixels where they are known
TOWARDS A LOCAL TRACE FORMULA
"... 1. Suppose that G is a connected, reductive algebraic group over a local field F. We assume that F is of characteristic 0. We can form the Hilbert space L2(G(F)) of functions on G(F) which are square integrable with respect to the Haar measure. The regular representation (R(yl, y2)4)(x) = ((yi1xy2) ..."

), E L2(, G(F)),, G(F), is then a unitary representation of G(F) X G(F) on L2(G(F)). Kazhdan has suggested that there should be a local trace formula attached to R which is analogous to the global trace formula for automorphic forms. The purpose of this note is to discuss how one might go about proving
Local Criterion of Quality for Color Difference Formula
"... It is important to be equipped with criterion of correspondence between color difference formula and experimental data of color discrimination of standard observer considering a quality of color printing or measuring. Such criterion is used to distinguish whether applied color difference formula is ..."

is good enough. A wellknown criterion is the value of ellipticity of MacAdam ellipses. In this paper we introduce a criterion based on newer and more thorough experimental data obtained by Wyszecki & Filder. We compare some well known color difference formulas using proposed criterion and show
LOCAL MOVE FORMULAE FOR THE ALEXANDER POLYNOMIALS OF nKNOTS
, 2005
"... Abstract. It is wellknown:Suppose there are three 1dimensional links K+, K−, K0 such that K+, K−, and K0 coincide out of a 3ball B trivially embedded in S 3 and that K+ ∩ B, K − ∩ B, and K0 ∩ B are drawn as follows. Then ∆K+ − ∆K+ = (t − 1) · ∆K0, where ∆K is the Alexander polynomial of K. ..."
