fft_matrix_shift R Documentation
FFT Matrix Shift
Description
This function rearranges the output of a 2D FFT by moving the
zero-frequency component to the center of the matrix. It is used
internally by AcuityView() to correctly align spatial frequencies.
Usage
fft_matrix_shift(input_matrix, dim = -1)
Arguments
input_matrix
The output of a 2D FFT.
dim
Integer. -1 gives the correct matrix shift for the
AcuityView function.
Value
A matrix with the zero-frequency component shifted to the center.
