Lattice Algorithms for Compression Color Space Estimation in JPEG Images
(20010801)JPEG (Joint Photographic Experts Group) is an international standard to compress and store digital color images [5]. Given a color image that was previously JPEGcompressed in some hidden color space, we aim to estimate ... 
Learning minimum volume sets with support vector machines
(20060901)Given a probability law P on ddimensional Euclidean space, the minimum volume set (MVset) with mass beta , 0 < beta < 1, is the set with smallest volume enclosing a probability mass of at least beta. We examine the use ... 
Lifting Construction of NonLinear Wavelet Transforms
(19981001)This paper analyzes nonlinear wavelet transforms using the lifting construction. The lifting construction exploits a spatialdomain, predictionerror interpretation of the wavelet transform and provides a powerful framework ... 
A Limitation of the Kernel Method for Joint Distributions of Arbitrary Variables
(19960201)Recently, Cohen has proposed a construction for joint distributions of arbitrary physical quantities, in direct generalization of joint timefrequency representations. Actually this method encompasses two approaches, one ... 
Limits of population coding
(20030720)To understand whether the population response expresses information better than the aggregate of the individual responses, the sum of the individual contributions is frequently used as a baseline against which to assess ... 
Locating Available Bandwidth Bottlenecks
(20040901)The Spatiotemporal Available Bandwidth estimator (STAB), a new edgebased probing tool, locates thin links  those links with less available bandwidth than all links preceeding them  on endtoend network paths. By ... 
LongRange Dependence: Now you see it now you don't!
(20021120)Over the last few years, the network community has started to rely heavily on the use of novel concepts such as selfsimilarity and LongRange Dependence (LRD). Despite their wide use, there is still much confusion regarding ... 
Low Rank Estimation of Higher Order Statistics
(19951201)Low rank estimators for higher order statistics are considered in this paper. Rank reduction methods offer a general principle for trading estimator bias for reduced estimator variance. The biasvariance tradeoff is analyzed ... 
MBand Multiwavelet Systems
(19990320)In this paper we investigate multiwavelet systems whose scaling functions have disjoint support. We demonstrate that, with the exception of a trivial case, this property may not be attained by two band multiwavelet systems. ... 
Magnitude Squared Design of Recursive Filters with the Chebyshev Norm Using a Constrained Rational Remez Algorithm
(19941001)We describe a Remez type exchange algorithm for the design of stable recursive filters for which the Chebyschev norm of H(w)  F(w) is minimized, where H(w) and F(w) are the realized and desired magnitude squared frequency ... 
Magnitude Squared Design of Recursive Filters with the Chebyshev Norm Using a Constrained Rational Remez Algorithm
(19940501)We describe a Remez type exchange algorithm for the design of stable recursive filters for which the Chebyschev norm of H(w)  F(w) is minimized, where H(w) and F(w) are the realized and desired magnitude squared frequency ... 
Magnitude Weighting and Time Segmentation for PhaseOnly Reconstruction of Signals
(19810401)Phaseonly reconstruction of signals and its application to blinddeconvolution were introduced recently by Oppenheim, and by Hayes, et.al. In this report, we briefly present another description of this phaseonly ... 
Marginals vs. Covariance in Joint Distribution Theory
(19950501)Recently, Cohen has proposed a method for constructing joint distributions of arbitrary physical quantities, in direct generalization of joint timefrequency representations. In this paper, we investigate the covariance ... 
A Markov Chain Analysis of Blackjack Strategy
(20040701)Blackjack receives considerable attention from mathematicians and entrepreneurs alike, due to its simple rules, its inherent random nature, and the abundance of "prior" information available to an observant player. Many ... 
Matrix Based Computation of FloatingPoint Roundoff Noise
(19891201)A matrix based procedure is presented for computing the output roundoff noise power for filters implemented with floatingpoint arithmetic. The filter's computational structure is represented in terms of a product of ... 
Measurements vs. Bits: Compressed Sensing meets Information Theory
(20060901)Compressed sensing is a new framework for acquiring sparse signals based on the revelation that a small number of linear projections (measurements) of the signal contain enough information for its reconstruction. The ... 
Measuring TimeFrequency Information and Complexity using the Renyi Entropies
(19950901)In search of a nonparametric indicator of deterministic signal complexity, we link the Renyi entropies to timefrequency representations. The resulting measures show promise in several situations where concepts like the ... 
Measuring TimeFrequency Information Content using the Renyi Entropies
(20010501)The generalized entropies of Renyi inspire new measures for estimating signal information and complexity in the timefrequency plane. When applied to a timefrequency representation (TFR) from Cohen's class or the affine ... 
Minimax support vector machines
(20070801)We study the problem of designing support vector machine (SVM) classifiers that minimize the maximum of the false alarm and miss rates. This is a natural classification setting in the absence of prior information regarding ... 
Modelbased Inverse Halftoning with WaveletVaguelette Deconvolution
(20000901)In this paper, we demonstrate based on the linear model of Kite that inverse halftoning is equivalent to the wellstudied problem of deconvolution in the presence of colored noise. We propose the use of the simple and ...
