# EE381K-14 Multidimensional Digital Signal Processing -
Frequency Domain

Lecture by Prof. Brian L. Evans

## Announcements

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

## Lecture

## Supplemental Information

- ImagePhaseDemo.m to show
the importance of phase in image processing.
The script generates four plots in four different windows:
- Original image
- Image corresponding to magnitude of FFT of original image
- Image corresponding to phase of FFT of original image: real component
- 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.
