EE381K-14 Multidimensional Digital Signal Processing - Frequency Domain

Announcements

• Homework #1 is due on Thursday, January 24th, in class.

Lecture

• Lecture on the Two-Dimensional Frequency Domain in PDF, Postscript, and HTML formats

Supplemental Information

• ImagePhaseDemo.m to show the importance of phase in image processing. The script generates four plots in four different windows:
  1. Original image
  2. Image corresponding to magnitude of FFT of original image
  3. Image corresponding to phase of FFT of original image: real component
  4. Image corresponding to phase of FFT of original image: imag component
  Since the phase of the FFT of the original image is complex-valued, two images (real part and imaginary part) are needed to display it.
