Detailed Description

a filter to perform an FFT on an image

Typical usage:

Filter::FFT fft (input);
auto output = Image::create<complex_value_type> (fft, argument[1]);
fft (input, output);
static Image open(const std::string &image_name, bool read_write_if_existing=false)
Definition: image.h:189
void fft(ImageType &&vox, const size_t axis, const bool inverse=false)
Definition: fft.h:163
vector< ParsedArgument > argument
the list of arguments parsed from the command-line
