Calculate fft amplitude
Description
Calculate fft amplitude
Usage
fft_amplitude(im, modify = FALSE, dc_value)
Arguments
im
an image
modify
if TRUE, amplitude value is log-rescaled, which is useful for plotting purpose
dc_value
if given, DC (direct current) component is replaced with this value
Value
an image
Examples
amp = fft_amplitude(im_gray(regatta), modify = TRUE)
plot(amp)
