WebJul 17, 2024 · Phase in an FFT result also contains information about symmetry: the real or cosine part represents even symmetry (about the center of the FFT aperture), the imaginary component or sine part represent anti-symmetry (an odd function). So any photo or image would get its symmetry hugely distorted without full FFT phase information. ray white mount maunganui https://boom-products.com
