What is the result of performing a Fourier transform on the Fourier transform of animage? Try it out. Can you explain the result?

Expert Solution
Step 1

Fourier redesign is an important image processing tool used to convert image into its sine and cosine components. The transition effect represents an image within the Fourier or frequency range, at the same time due to the fact the inserted image is the same position.

within the Fourier regional image, everything represents a certain frequency contained within the local image.

 

Fourier remodel is used in a wide variety of programs, including image processing, image filtering, image reconstruction and compression.

Since we are very effective in virtual photography, we are able to limit this expression to Discrete Fourier redecorate (DFT).
