swdft2d function

2D Sliding Window Discrete Fourier Transform

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.

Returns

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