Description

2D Sliding Window Discrete Fourier Transform

Usage

1
swdft2d(x, n0, n1, type = "fftw")

Arguments

x

2D input signal

n0

window size in row direction

n1

window size in column direction

type

algorithm to implement. defaults to "fftw", other option 'fft' for R's base FFT function. R's base fft function is used if 'fftwtools' library is not installed.

Value

An S3 'swdft2d' object. See ?new_swdft for details.
