Two-Dimensional Fast Fourier Transforms in Image Processing

摘要

This report is intended to orient the reader to the application of the discrete two-dimensional (fast) Fourier transform in the context of digital image processing. Both mathematical and pictorial results (magnitude, phase, and power spectral density plots) are presented for a variety of rudimentary and more complex images. In addition, the VIPER (Visual Image Processing, Enhancement, and Reconstruction) digital image processing facility of the Air Force Aerospace Medical Research Laboratory is described. (Author)
