# Edge detection in images using Fourier Transform

Often while working with image processing, you end up exploring different methods to evaluate the best approach that fits your particular needs. I am going to talk about one such approach here, Fourier Transform.

# What is Fourier Transform?

In the simplest terms, a Fourier Transform helps in breaking down an incoming signal into its building blocks. For example, consider a signal f(x) having made by superimposing two or more sinusoidal functions with different frequencies. Now by just looking at the plot…
