Features

Default Page

Upload images

Display magnitude and phase of each image in fourier domain.

Select magnitude or phase component of one image only to display uniform magnitude or uniform phase of image in time domain.

Select magnitude or phase component of each image and display the mixed image in time domain.

Crop in magnitude or phase of each image and show the crop effect on the mixed image on real time.

Tools

1. Frontend :

• React Js
• CSS

2. Backend :

• Python
• Flask

Theoretical Technique

Fourier Transform

• Fourier transform of 2d images and calculating Magnitude and Phase of images.

• Fourier shift for visualizing Fourier transform with the zero-frequency component in the middle of the spectrum.

• Mixing magnitude and phase of diffirent image in fourier domain.

• Inverse Fourier Transform of mixed image to display it in time domain.

Project Structure

Image Class:

• Contains all image information and methods to :

1. Read and resize image.
2. Claculate fourier transform of image.
3. Crop in image phase and magnitude.

Processing Class:

• Contains static functions and static objects of Image model to store data.
