Introduction

In this lab you'll learn about Fourier domain image operations and explain their effects on the images. You'll compute the 2-D Fourier Transform of an image, perform some operations, then take the inverse 2-D Fourier Transform. There are 3 parts to this lab, each part examines a different operation done in the Fourier domain.

1. Examine what happens to an image when you set the phase of each frequency component to zero, but preserve the magnitude.

2. Examine what happens to an image when you eliminate the variation in the magnitude of each frequency component, but preserve the phase.

3. Examine what happens when an image is low pass filtered.
