We describe an extension to the “best-basis” method to select an orthonormal basis suitable for signal/image classification problems from a large collection of orthonormal bases consisting of wavelet… (More)

We introduce a randomized procedure that, given an m×n matrix A and a positive integer k, approximates A with a matrix Z of rank k. The algorithm relies on applying a structured l×m random matrix R… (More)

We propose a shift-invariant multiresolution representation of signals or images using dilations and translations of the autocorrelation functions of compactly supported wavelets. Although these… (More)

The authors previously developed the so-called local discriminant basis (LDB) method for signal and image classi3cation problems. The original LDB method relies on di4erences in the time–frequency… (More)

Methyl jasmonate (MeJA) as well as abscisic acid (ABA) induces stomatal closure with their signal crosstalk. We investigated the function of a regulatory A subunit of protein phosphatase 2A, RCN1, in… (More)

In this paper we describe a new technique for detecting and characterizing ellipsoidal shapes automatically from any type of image. This technique is a single pass algorithm which can extract any… (More)

Time–frequency representations of a signal can provide a useful means for obtaining parameter estimates for signals consisting of various chirps. We demonstrate the utility of including edge… (More)

Electromethanogenesis is a new bio-electrochemical reaction potentially useful for energy conversion. As a first step toward its technical application, electromethanogenic reactors were built, and… (More)
