Web14 mei 2015 · Thus, since for typical optical images (e.g., the one you are looking at), where most the spectral energy is low frequency, the phase-only image is devoid of low frequency content. As for the magnitude-only image, remember that location in the image domain is tightly coupled with phase in the frequency domain. http://howthefouriertransformworks.com/understanding-the-output-of-an-fft/ WebFrom the complementary perspective, the magnitude estimation branch is designed to filter out dominant noise components in the magnitude domain, while the complex spectrum purification branch is elaborately designed to inpaint the missing spectral details and implicitly estimate the phase information in the complex-valued spectral domain. characters in aladdin 2019
