Nonuniform

EDFT (Extended Discrete Fourier Transform) algorithm produces N-point DFT of sequence X where N is greater than the length of input data. Unlike the Fast Fourier Transform (FFT), where unknown readings outside of X are zero-padded, the EDFT algorithm for calculation of the DFT using only...

Web-based seminars were broadcast live on 03 March 2004. The topic involved custom analysis of image data for scientific problems using MATLAB, along with the Image Acquisition and Image Processing toolboxes.The particular example shown was a particle size analysis using an example image - light...

The Matlab code in this folder implements 1D-3D NUFFTs via fast Gaussian gridding. The convolution loops are written as C programs to be compiled as mex files from the Matlab command prompt. Further mathematical details about the code can be found in L. Greengard and J. Lee, "Accelerating the...

nu_corrector is a tool for correcting intensity non-uniformity artifact of image. Here, non-uniformity refers to image artifacts of vignetting and bias (e.g. intensity inhomogeneity, illumination etc.). This tool is an implementation of our single-image based vignetting or bias correction systems...

A peak fitting program for time-series signals, written as a self-contained function in a single m-file. Uses an non-linear optimization algorithm to decompose a complex, overlapping-peak signal into its component parts. The objective is to determine whether your signal can be represented as the...

RanLip uses acceptance/rejection approach to generate random vectors, which is based on approximation of the probability density function from above with a "hat" function. It is assumed that the distribution hasLipschitz-continuous density, which is either given analytically or has a black box....
