Creating Hybrid Image with Matlab

In this tutorial, I’m gonna show you how to create hybrid images . Basically, you need to filter your first image with high pass filter and the second image with a low pass filter and then add theses two images. The following code shows how to do that. The full code is available at my GitHub.

 

   
 

 

 

 

Displaying Adjusted Frequencies of signal with Fast Fourier transform

In this tutorial, I will show you how to get Fast Fourier transform of a signal and then correctly display the signal. Link to the code in my Github repository.

 

Signal in time domain

 

Getting Fourier transform of the signal:

The signal in frequency domain (Bins)

 

The signal in frequency domain consists of 60Hz and 120Hz.
